I have a service manual and I've gone through the self diagnostic program which shows the sensors to be ok. I know I have to go through and start checking connections as the manual instructs.
I have checked the two fuses and the relay on the left side of the dash which are all fine.
I'm thinking the next thing to check is the fan control amplifier.
My question is... Has anyone else here experienced this problem and what did it turn out to be? Are there any common problems maybe I should check first before I go tearing up the dash?
Thanks,
Andrew

It is the only malfunction/repair I've made to our Pathy since it was new. The fan amp seems to be a weak link (a very common issue) since it is a small computer board that heats up and although it has a built-in "radiator", it just gets too hot and fails. Luckily, an easy fix and an easy DIY (though not cheap).
Typically, when the fan amp fails, it loses it's ability to act as a rheostat (on auto. climate control models) and reverts to high speed only. That's how mine acted up... no variation in speed... just on full blast with no way to shut it off.
While what you describe is somewhat different, I'll bet it's a malfuntion of the fan amp control board. Just replace the part.
Good Luck!

Step 1: Open the glove box and use a common screwdriver to gently pry the plastic retainer with the cord off the right side of the glove box (while it's open). It should come off without much of a hassle.
Step 2: There are two plastic pins, one on each side on the bottom of the glove box. They have a part that sticks out and should be easy to find. Just push them towards each other, one at a time. Once out, the glove box will come out.
Step 3: Unscrew the two phillips screws that hold the wood trim piece (on a QX4) on and then gently work it free by pulling it up and out.
Step 4: Remove the other phillips screws around the panel (I think there are about 7 more) and the plastic panel should come out. Watch for a wire that goes to the glove box light, it needs to be disconnected with a simple turn before the panel is completely free.
Step 5: Insert the common screwdriver into the left side of the wiring harness that goes into the amplifier and gently pry it and pull it out. (The fan control amp. is white plastic, about 2 1/2" tall, with a phillips screw on the top and bottom with a wiring harness that goes into it).
Step 6: Unscrew the two phillips screws from the fan control amp. and it should come right out.
Go in the reverse order to put back together.
It'd be a good idea to replace the in cabin air filter (2 piece filter) when you do this as it'll be right there. Just pop the metal clip off the bottom filter, remove the bottom filter, let the top filter come down and then remove it. Replace in the opposite order.
You can get the in cabin filter (Nissan part #27275-2W625) from your local dealer or order it through one of the sponsers of the site. It should be about $20. I've ordered parts from Riverside (CA) Infiniti through Jason (he's a member of the forum too) and have been happy with the prices.

to Andrew224. My mom is looking to trade her 2001 QX4 in this week (possibly tomorrow) for either a new FX or EX. Well yesterday she called me up and told me that the AC had just stopped blowing air. I did a quick search on Google, found this site, did a search for my problem, and saw this post. Andrew224; your instructions were perfect !! I saved Mom a whole lot of money for a 15 minute fix. Granted I took some risk in just going right to the amplifier, but luck paid off.

I had this problem with my '01 Pathfinder, and had a mechanic look at it and he could not find the problem. I came across your post and instructions----found a genuine Nissan discount parts site, and ordered the part for $107.00 (inclucing shipping).
The part arrived 30 minutes ago, and it is installed and my a/c and blower motor are once again working. You probably saved me a good $500.00.
Many, Many thanks Andrew. A 10 year old could have put it in too!!!

The in-cabin filter traps quite a bit of dirt and debris and shouldn't be overlooked as optional as far as changing. It should be changed once a year or every 12k miles. It seems that the lack of changing the in-cabin air filter may lead to reduced air flow over the fan control amp. Which in turn could possibly lead to overheating and failure of this part.
I'm sure a lot has to do with the dealers charging over $100 to change this filter which is a tall order to do every year. But after you see that you can do it yourself for about $25, it tends to get changed more often. I know it has in my case!

The in-cabin air filters that I use are in Nissan Filter Kit 27275-2W625.
There should be nothing that needs to be cut. The filters are just to the left of that amp. you replaced. There is a small metal clip that needs to be popped off with a common screwdriver and the filters will slide out one at a time. They are stacked on top of each other. You can see the grey plastic edge of the filter next to the area where you were just looking. The filters may even have a part number printed along the edge. The filters fit in so that the air passes through them left to right and you will be looking at the skinny, hard plastic edge.
Let me know if you get it. If not, I can take a picture and send it to you. If that dash panel behing the glove box is out of the way as it would have to be to change the amp. It should take you no more than 15 seconds to switch out these filters. You should use no other tool other than a common screwdriver to do some gentle prying to get the clip off.
I hope this helps.

As far as where it's located, I really couldn't tell you. When I started poking around, I got a service manual and it walked me through it. I would suggest the same. If your mechanically inclined, it couldn't hurt to take a look yourself. Most likely it's behind the glovebox and it'll have a wiring harness going into it and it'll probably be screwed in with a couple screws. The part has a plastic top where the wiring harness goes into it but the rest of it is metal and is kinda long and vented to dissapate heat (as this part heats up frequently and leads to it eventually failing).
But like I said, I'm just an amature who figured it out on my own with the help of a service manual and the input of some other people here on this board.
Good luck.

I can only speak for '01s and newer as that is the model that I have. I've never worked on a '00.

After looking into this, I think these directions are for models that were not originally equiped with an in-cabin air filter. You actually cut out a hole to put the filters in.

Post Title: Replace Fan Control AMP and In-cabin Filter for 02 QX4 or Pathy (pic version
Posted by: Solara at 12:30 PM 5/2/2008
OK...my case is exactly like Andrew224. 50,000 miles 2002 QX4's fan blower decided not to work 1 day. (wife's car). I have test the AC button and did hear it "clicks" on and off. I have try to turn on full blast on the fan but nothing happen. So that fits perfectly like what Andrew mentioned above, I have to replace the Fan Control AMP. I am sure if your fan is blowing full blast without slowing down or adjustment, the same problem occur.
Parts....ordered (by phone) @ Courtesy Parts....just like Andrew and other mentioned...probably the cheapest area for genuien Nissan parts. I've talked to JOE there and ordered part # 27761-70T03 (Module Assy-Pow) . Also, I might as well change the in-cabin filter, however, the parts number listed above does not match what Joe had found. He said, this is a direct fit to QX4 and Pathy and the filter parts # is 999m1-VP003.
Total amount, shipped to Chicago area, within 2 days....$158 something.
Courtesy Nissan - http://www.courtesyparts.com/
You should CALL instead of order online, cause I can't find the filter online and I prefer to talk to real person to confirm my order instead of a computer.
OK...got the parts within 2 days...but I think anyone before ordering the parts, please follow my steps and see you are capable to do all these installation/removal by yourself. Not everyone is very car/machine friendly, so you might need to ask someone that know what he is doing or....saving money is not your option, you have to let the dealer to make your hard earning money. But honestly, I think this is a stage 3 (out of 10) DIY fix that even a 10 years old can do (like someone mentioned above...) So...follow these steps and see you can get to the stage that you can find the Fan Control AMP and remove it. If you can remove that AMP, then you can go order the parts and install it yourself.
Yes...your car can still run without the amp, just don't turn on your climate control and HOPE it is not 20 degree outside (you don't need AC, but you do need HEAT...)
Ok...here are the parts and how they look (and their parts number on box)
OK....step 1, open glove box, remove the stringer on side, simple step
Step 2...Flip down the 2 lower plastic pins, then yank them toward center. Pull harder and both pins should be out completely.
Step 3....remove 2 screws and get that plastic wood panel out of the way.
Step 4...remove all 7 screws.
Step 5...remove 2 more side screws
Step 6....if 1st time removing this panel, need to use some force to swing it out...don't be afraid, it is not that hard to pull it out.
Step 7....panel should be down.
Step 8....remove glove box light fixture, snap and pull, may be check the bulb as well, mine blew long time ago and it is the perfect time to replace that.
Step 9...you should see the whole picture, the FAN AMP and the In Cabine Filter...item # 1, 2 and 3.
Step 10...unplug fan amp wire plug
Step 11...remove 2 screws. The AMP should be about to slide out without any trouble. If you have the new AMP parts, replace it in reverse order.
Step 12....if you have the new AMP in...it is a good idea to start your car and try out the climate control system JUST to make sure the AMP does take care of your problem (mine does...awesome)
Step 13....remove filter clip at the bottom. Slide the lower panel 1st, then the upper panel.
Step 14....use the already came with clip (with the new filter), plug in new filers, clip in new clip....
Step 15....if you want, you can fill out the "Date tag" and the filter notes and stick them onto the panel like mine. It is totally optional, not required but it is there, might as well do it...
Ths is it...follow all the steps in reverse order and you are done. This site and Andrew224 (and others) just saved me $700 because the local dealer said they have to do all the testing, this and that....total was $900 plus TAX and I have to leave the car for 2 days there and they don't have any opening untill early MAY...
Good to save money...and better, good to share with others and help others to save more money...

The Pathy does not come standard with cabin filters. If you want to install them, then yes, you do have to cut/remove the plastic knockouts where the filters go. I had to do that on my 02 Pathfinder. The knockouts are there to prevent air leaks when there are no filters installed. The filters I bought by the way, came with clips.

Posted by: bstaron at 11:07 AM 7/7/2008
But then, I traced the circuit and found the control signal passed through a small component also mounted to the heat sink, which I couldn't identify. So on a whim, I shorted across this component... and my fan started running!
My best guess is that this component is a thermal cut off switch. Built to burn out if the heat sink gets too hot. (Now, they could have put in something with a reset button, but then they couldn't sell an expensive replacement part.)
I decided to replace the unknown part with a 10 K ohm resistor. It works with the new Mosfet just like new. I don't know if the original Mosfet was even bad... probably just the 'strange' part burned out. But since it is working, I didn't bother swapping back the old part to test it.
I'm going to look to see if I can find a replacement thermal cut-off component, but until then... it works!
Here are the steps:
1. Follow the excellent pictures from Solara's post to remove the fan amp.
2. Remove the white plastic cover from the fan amp.
3. Unsolder the 3 connections on one end of the circuit board and the two connections on the other end. (Melt the solder while gently lifting the circuit board and work your way around making a millimeter progress or so at each connection until all are free.)
4. Remove the screw holding down both components to the heat sink.
5. Remove the 'strange' component (the one with two leads).
6. If needed, replace the Mosfet... you may not need to. If you do replace it, use thermal grease. The whole heat sink gets REALLY hot... you want good conductivity. You can probably get thermal grease from Radio Shack.
7. Tighten the screw back down. If you replaced the Mosfet, you may need to add a washer, as the replacement part is physically smaller than the original.
8. Solder a wire or a resistor (0 - 10K ohm) onto the circuit board at the two-connector end (where the 'strange' component was removed). The resistor need not be physically mounted to the heat sink as was the 'strange' part.
9. (Optional) solder short insulated jumper wires to each lead of the Mosfet, so if you need to disassemble this part again you won't have to repeat the pain of going through step 3.
10. Solder the 3 Mosfet leads (or the jumper wires) back onto the circuit board.
11. Reassemble and mount back in car.
12. Better change out the filter (again, see the pictures above), since the clogged filter probably caused too little air flow, which caused the fan amp to overheat, causing the thermal fuse to blow in the first place. (I think I'll try using some material from a home furnace filter, under $2, stuffed into the original plastic frame rather than pay $20+ for the replacement part.)
13. Test it out... hope it works for you!
14. Legal disclaimer... how stupid that lawyers have forced us into this... the 'strange' part may be crucial to the safe operation of this system. By removing it, you may be placing property and perhaps lives at stake. I do not know the original purpose of this part. Its removal may burn out the whole electronics section of your car. It may allow the fan amp part to overheat and melt the surrounding parts or even start a fire. It may void your vehicle's warranty. (If you believe in chaos theory, it may cause world war 3.) Concern over these effects could raise your blood pressure and perhaps cause a heart attack and possible death. On the other hand, it may just work.

I've never heard what you've been told. In fact, when mine went out in my truck (an '01 QX4) about 3 months ago, I took it to the dealer (it's under an Infiniti extended warranty) and they just replaced the fan amp.
My opinion is that unless your truck is under warranty, which it doesn't sound like it is or you wouldn't be here, you should just replace the fan control amp. yourself and save a few crisp hundred dollar bills.

I replaced the failed component within the metal case (making sure to properly re-heat sink the replacement component since all fan motor current is driven through this small part). You will have to solder the part into place, but there are only three pins on the part, so it's a fairly easy repair. The repaired amp module has worked perfectly fine. We haven't had a problem in over a year now. The replacement component costs about $3.
That takes the repair of this problem from a $700 dealer repair, all the way down to a $3 component replacement if you are willing to get out your soldering iron. Use the directions from another author in this thread to remove the AMP module metal can (The pictorial instructions provided in this thread are excellent). Then open the can and find the only part that looks like the one pictured in the link below.
A link to the replacement part follows:
http://parts.digikey.com/1/par....html
This fix took the $700 dealer repair beyond the savings of going with the $120 module replacement - all the way down to a $3 component replacement.
By the way, there is also a thermal fuse in the module. Mine checked out ok with the ohm meter, but I replaced it also anyways since I had the module opened to replace the MOSFET. The part number I used for that component follows:
http://parts.digikey.com/1/par....html
I hope others can have the same success in savings I had with this repair.

I have a 2003 Pathfinder and bought the parts at Courtesy. Delivery slower than I would have liked, 4 business days, total cost for fan control amp and filters was $156, delivered. The 2003 Pathfinder is also one of those where you have to cut out the hole for the filters. If I had done my homework and realized this ahead of time I would not have installed them. Trying to cut a clean hole in the plastic so that the filters fit nicely was a PITA. I have done without them all this time could have continued without them. Unless you have severe alergies or other reasons to want them I suggest doing without.

Also, when I ordered the Fan Control Amp I also purchased the cabin filters. There are no provisions in the housing to accomodate these filters. I read in a previous post that it may be necessary to cut slots in the housing in order to use these filters. Is this indeed the case?

Do you have the digital (automatic) heating/air system or do you have the three dial (manual) heating/air system? If it's the latter then the above paragraph applies to your vehicle. If it's the former, then everything I have said here does not apply.

| You are absolutely correct in that the HVAC controls are manual. Is the resistor unit difficult to change out and where is it located? Thanks! |
The blower resistor is actually very simple to replace and only takes about five minutes and no dis-assembly is required! If you look under the glove box area you can see the blower motor. The blower resistor is located on the other side of the blower motor (on the firewall side) and it's held in with two screws. You just have to remove those two screws and pull out the blower resistor. Here's a diagram to help you locate it better:
If you have a multimeter you can test the terminal resistances to see if this is actually your problem.

Thanks so much. I just had the same problem with my 2002 Pathfinder a couple days ago. Thanks to your information here I fixed it today for just under $200 and about 20 minutes.
Another strange problem I have is that my car loses oil. It doesn't leak and there is no smoke in the exhaust. I found other sites saying it was a defective right valve cover. Have you heard of that?
Actually, there is another hard problem to diagnose. My dash lights are half out but not all the time. Most of the time my MPH is lit but my Tach is not. Then whenever it feels like it, the whole thing is illuminated. I have no clue where to look for that one.
I appreciate any insight you may have.

Thanks for all of the help first.
I have a 2001 Pathfinder LE V6 and have had the same problems of my blower not working. Ther was no voltage to the blower motor. So as everyone had done I took out the fan amp and found in my case that the thermal cut off fuse was blown.
For everyone's reference the N-Channel MOSFET was an NEC K2500 9Z
The thermal cut off fuse is a Panasonic N-Series EYP2BN134. I had a lot of trouble finding them so I ordered:
Cantherm SDJ1 DF141S
Digikey Product Number 317-1134-ND
I just ordered this new thermal fuse and have NOT tried it out yet. Since the specs appear to be very similar it should work. I'll report back once I test it out.
By the way when removing the circuit board use a flat screw driver and pry up on the side where you can see the little screw holding the MOSFET down on the heatsink. The side there there is a single brass connector (labeled R1/R2). Then use a small screwdriver and remove that screw. The lift vertically up to disengage the thermal paste which is very thick in consistency.
Hope this help everyone. I'll report back soon.

My wife has an 05 pathfinder and the blower is working intermittently. It doesn't run when you first start or drive, but then about 15 minutes into your ride it usually starts working and works fine on all speeds until the vehicle is turned off. It has the digital controls and nav system, but I believe it is a "manual" blower fan system as from what I've read and the diagrams I've seen, I can definately see the resistor module with a 4 wire white clip going to it under the glove box on the passenger side next to the blower motor. However when I test the blower motor, I am getting 12 volts and power to it through the blue wire. Power goes away when I turn the fan off through the controls. So if I am getting power to the blower, then the resistor module should be working, right? Just not sure if I should change the blower motor or module and wanted to get some feedback.
Thanks!

| Changing the blower motor was very easy using the instructions above to remove the glovebox/paneling and took about 30min. I found a motor online at https://www.am-autoparts.com/ for $55.55 free s/h and it arrived in2 days! |
I have to same issue ! I have to turn the air/heat on and off a few times before the sound stops. And sometimes it still doesn't stop. Def want to get this fixed before the winter.
I'll order the motor thanks to your post!!
