AC compressor clutch not engaging

Postby weekend warrior 71 » Sat May 02, 2020 10:55 pm

Hello, I'm trying to help out a coworker with her car, a 2008 Nissan Rogue with approximately 130k miles. She said the AC was blowing hot with the AC set to max. I have done some preliminary diagnosis on it and could use some advice. The compressor clutch is not engaging no matter how long I watch it on a 70 degree day with AC set to max. I have verified the controls are moving the actuators on the blend door and the blower is changing speed ect... The owner indicated she just had the blower motor replaced this last winter and I don't think the guy did a very good job. The screw holding in the blower wasn't even put back in. She had it into the guy twice, the first time she got it back, she complained the fan was making a loud noise and then he said it was the fault of an after market cheap fan. He charged her more saying he would install an OEM one. I think he didn't have it set in the housing correctly causing it to rub and he only had to reset it to fix it. Is there something he could have screwed up that would cause the AC not to work?

The low pressure side does not get cold and when I hooked up the cheap can of Freon gauge to it, it went to around 85 or 90 psi in the red without the clutch engaged. Today I hooked up my manifold set and confirmed 90 psi on both the high and low side, still no clutch. That pressure seems normally high with no clutch engaging. I did try to add a bit of Freon, but it doesn't seem to be drawing in any. There is no evidence of leaks and seems like it should be working with the amount in it. I will check tomorrow for voltage at the compressor connector. I've read on this forum of the computer test with the door switch, I will try that too. I've read as well that the pressure switch can be jumpered to check if the compressor clutch will engage. I'm not sure if it is a 2 or 3 pin connector, if it is a 3 pin, which 2 get the jumper? Any other suggestions would be greatly appreciated. In my experience, the owners on these forums usually know more than most dealerships so I'm hoping for your help.

Thanks in advance!

:welcome:

Sounds like you're on the right track. I didn't see it mentioned, but did you check the fuse? And given the description of the work the other guy did, he may have damaged something along the way (let's hope not).
If the clutch doesn’t engage, the problem could be a blown fuse, an open in the wire to the clutch coil, a bad clutch coil, a poor ground, or a low pressure lockout.

I don't know if you know this, but here at NICO, we have Factory Service Manuals available free to members. Here's the direct links to the HVAC sections for the '08 Rogue.

Thanks Rogue One. Looking under the dash, I don't know what he could have damaged, there isn't much there that a bull in a china shop could break. He definitely cut corners on the job including breaking plastic clips and stuff, just sad. As to the fuse, I looked in the fuse blocks but I could not find any fuse labeled AC. I forget what it said but there was one 10 amp fuse in the cabin I thought might be it but the fuse was fine anyhow and 10 amp seems too small anyhow. Will have to do more digging to find where that fuse is, I was starting to think Nissan did something weird and didn't need one.

Googling for info led me to NICO and seems to be the foremost on Nissans. I think I saw on one post about the service manuals being here, just hadn't found them, so thanks for the links, that helps. I love car forums, those of us that prefer to fix our own rather than get ripped off by dealers need to stick together.

That stinks, I even opened that compartment partially and looked down and didn't see fuses so I thought it might be the computer compartment. Crossing fingers that it is the silly fuse, that would be glorious. I performed the door switch test and I did not hear the compressor clutch try at all. The horn beeped, windshield wipers went, headlights on and off, then fan revved up. No clutch test on compressor in that cycle that I could hear. I let the cycle go 3 times but nothing. Where in the cycle should I hear the clutch engaging? I don't know if I did something wrong, do I dare put my hand down on the compressor to try feeling the compressor clutch sliding? I'm thinking just putting 12 volts to the compressor and bypassing everything to see if the clutch will engage for a second.

A bit off topic and I apologize for that. I am curious if there are other Rogue standard maintenance things I should look at that owners just know that know these cars. I am an S series Saturn nut and know that car inside and out and know what work around maintenance things need done such as knocking the carbon off the throttle body once in awhile, ect.. Do Rogues have some standard tricks to keeping them tip top that she may have not done and the dealer doesn't do on her oil changes? I figure while I got it, go through it to do any tune up stuff that is just simple easy things before giving it back to her.

Hmm, unfortunately not the fuse. The relay is in the computer so no help there, correct? I wish the compressor had a female plug on it to make jumpering it easier, I have to try scavenging a jumper somehow off old harnesses. Will report back on that. Would be easier if I had four hands. There are three wires off the ac pressure sensor, which two get jumpered to test that bypass? That would be easier than jumping the compressor I think but I don't know which wires. I think the wires were blue, white and yellow.

Update, I know I have 12 volts at the harness going to the compressor. I have been unable to get 12 volts directly to the compressor bypassing the harness to try engaging the clutch. That location and the small dinky connectors are impossible to know if I have a solid connection or not. I scavenged two small female connector pins from an old harness, insulated them and stuck them on the male pins of the compressor connector. I think I had a solid connection but so hard to tell down in there. I wish this were a gen 1 Rogue with the easier harness to jumper that I keep finding posts about. I've already hit the fan twice with my hand trying to get 12 volts to the compressor, just too tricky to know if I have good connection and kind of dangerous.

I think my hope is finding which two wires to jumper at the pressure sensor, any ideas?

Ok, so in conclusion I think I have my answer. The clutch failed to activate during the door switch computer test, it did not engage when directly supplied with 12v when jumpered to the battery, and now it measures Infinity measuring across the two pins on the compressor meaning it definitely has a bad coil or something internal. That just sucks. I figured it is so rare that clutches go out before bearings/seals killed the compressor. I've thrown every test I can except using my scanner, that is in the car I lent to my coworker, to check the live data to see if there is voltage at the pressure sensor. I am certain all other components are good since it is commanding 12 volts at the compressor harness. Now I get to give the bad news to my coworker. If anyone has any other tests I should throw at it, feel free to chime in, I would love to be proven wrong and have it be something easier.

Okay, that's a lot of territory you've covered, so I'll try and tackle some of it.

I think in your 6th post you meant to say 2nd gen, as the 08's were the very first Rogues. You know, it takes all the fun out of it if they're easy to work on. :chuckle:

Anyway I'm gonna be the bearer of bad news and say that you'll probably need to perform last rites on the compressor. Yeah it sucks that a component that normally lasts longer on other vehicles took a dump sooner than it should have, but that's been par for the course for Nissan for about the past 15 or so years.

When you get a moment read the comments people left here: POLL: Would You Buy Another Nissan?

Here's another thread worth reading: I AM DONE WITH THIS BRAND!!!--- Rant!

The CVT's in the 08, 09 and 10's were really problematic, so much so that Nissan had to extend the warranty on them. Nissan recommends that the CVT fluid be checked every 30k miles. The engine is pretty solid, so I can't recall any major issues that need tending to. Otherwise most everything you'll need to know can be found under this heading: 08-13 ROGUE DIY REPAIRS & MAINTENANCE, FAQ & INFO, TIPS, etc

Sweet, you guys run a pretty tight forum. Thank you for the feedback, sometimes having that knowledge base and sounding board can make or break a DIY project. I will read through the posts for sure. Sorry for the mix up in gens on my post, obviously I'm not that up on Nissans in general. Thankfully standard knowledge base applies minus the hidden fuse box. I know Nissan had their flop with their CEO being crooked but didn't know it was that bad.

Thanks again, if she keeps the car, I may be back later to pick more info up. I think I will stick to my Saturns myself, so much easier in my opinion except where they stopped making them... Every car has its quarks and an owner just has to learn them.

Cool beans.

Oh, I forgot to mention. One of the WORST cars I've ever owned was a 1992 Saturn SL1. To this day we still make fun of it's abysmal turning radius. I mean it's pretty laughable that a GMC Safari had a tighter turning radius than the Saturn. Only car I've ever own that had to have the tranny and the rack and pinion system rebuilt. :mad:

The clutch on these compressors fail, I replaced mine last year for exactly the same issue, no engagement. With a set of long nose snap ring pliers and a couple of sockets you can get your friend back in business. Here is a short diy explanation, in post #2.

post6802594.html?hilit=Ac%20clutch%20re ... t#p6802594


Here is a fix kit from amazon. Double check the model number on the compressor make sure this kit fits, all I did was do a Nissan Rogue 2008 search and there may be more than one compressor for that model year.

https://www.amazon.com/Compressor-Clutc ... NrPXRydWU=

Notice the small shims in the kit make sure you put them back in exactly the same order as they come out, so pay attention when you disassemble the clutch assembly. They give you extra shims usually so don’t feel compelled to use all of them.

Thank you, I was in fact just considering this option. Normally I consider fixing a compressor to be a lost cause, but since the seal isn't leaking, I thought it was worth looking into. Where do they hide the number on the compressor though? Hard to get down near the compressor without taking things off. I spent a decent amount of time watching vids on servicing and think it is straight forward enough and hopefully can be done while still in the car connected. Bonus if I don't have to have the system drained.

The reviews on the Amazon one are horrible though. I was already looking at this one on Ebay, thoughts?

The eBay one looks fine, I just linked that amazon one so you’d know what to look for if you had no idea what I was talking about.

You do not have to open the system, you don’t even have to take the compressor loose from its mount. Once the front tire and fender liner are off the compressor is right there in front of you. This is actually a relatively easy job on the Rogue. I’ve done this on my vw and I have to take the compressor loose from its mount and lower it, still attached to the lines of course, it just takes a little more time and effort.

The clutch is actually an electromagnet and they eventually short out and stop working, at that point most dealers and garages say “you need a new compressor “ which will cost anywhere from $400-1200 plus labor. It’s not unusual to have a total bill between $1000-2500, vs a 30 minute job with a $50 part.
,
Make sure you have a good set of long nose snap ring pliers. Make sure when you put the new snap ring in that it’s fully seated in the groove. Watch where the shims are and the thickness, I usually reuse the old ones, replacing them in the same order and position that they came out.

Rogue One has the part numbers for you, he always seems to know where these miscellaneous tid bits of info hide.

Sounds great, thank you guys. I will order the one off ebay. I tried to find the part number on her compressor for confirmation but I couldn't find it I'm just going to go for it, I'm sure it is the orginal one. I will report back when I get it in. Thanks for confirming this isn't too bad of a job. I was dreading a solidly pressed in bearing needing very special tools. Snap ring pliers I have but didn't want to buy some special tool for a one time use application.

Hey all, sorry for the delay. Had to wait for parts and then access to the car. I got in the parts on Thursday and it was the problem. Compressor works great now. The old coil was actually singed like it had been burnt or on fire at some point. What a poor design on the three screws holding in the coil though. Who puts phillips heads on torqued applications. The heads immediately stripped out from being on there too tight and even heat wouldn't budge them. I ended up using left handed drill bits to drill into the head and rip them out. Thankfully the kit I ordered had new screws. Hopefully I never have to do that again, it stunk to get them out. Other than that, not too bad and AC works great now.

Thanks again, having you guys as a sounding board helped immensely :)

In summary to anyone that comes to this thread later looking for answers to their own AC compressor not engaging, Ohm the connections on the compressor. If it isn't around 3.7 Ohms, the coil is dead and is a 50 dollar fix. I still can't believe this is a normal problem on these cars, just odd.

I was hoping you’d chime back in and let us know how it went. I’m glad you got it. Fortunately I didn’t have any problem with those 3 screws, they came right out for me, so that would definitely be a point to consider if others plan on doing this repair.

Even with the trouble you just saved yourself at least a $1000 dollars parts and labor. Good job.
