Silvia Digital Climate control Instructions................

[positron1]

I mounted the havac motor but I think that I am missing something because there is no way to connect the swing arm to the lever that actually opens the door. Anybody got pics or milk?

[positron1]

Anybody happen to have an extra havac motor swing arm linkage laying around that they want to get rid of???

[iiymij]

Finally got pictures of this and heres what I got with mine so far:



Dunno if this thread is still alive and let me see if I got it right guys

1 - Fan relay, keep this JDM one plugged together disconnect USDM one 2 - Cabin temp sensor, Beatupsx glued his to the coin holder on then cut some slots in the holder for air to flow through. 3 - Sunload Sensor - Drill a hole through defroster vent and plug in, mine's missing the cap so I gotta make my own 4 - the mix door motor mounts towards the bottom of air box behind the control unit 5 - This red plug goes to your USDM red / black wire on the USDM 3 wire harness 6 - Large white harness with about a gajibillion wires to it, re wire the Green White wire from ( #8 on the picture ) to this harness 7 - plug and play 8 - Move a Green and White wire from here to the large harness with lots of wires ( #6 on the picture )

Things to also do

- Ground Red/Yellow wire from the large USDM harness (GND-)* whatever that means but maybe someone here can help me out with this

Now what else to do that I am missing so far and have no clue?

Questions I have right now are

- how do I hook up the JDM blower resistor when I get one

- how I install Ambient air temp sensor ( from 91 pathfinder and most mid 90's maxima) when I get one

PS how do i use the browse button to add pictures?

bump* and

For number 4 the air door mix motor correct?

I've been trying to install the thing to the back but I don't have that gray rod that goes with it? Do I need it or how would I make it fit my USDM part?

for my USDM it has the same looking unit but for the white part its got this nub on a track of some sort? Am I missing something here?

At the back I've also got this black box or plug + harness and I have no idea how to remove and then move it, I don't see this part in any of your guys pictures so I was wondering is my 240sx different?

mines a 92 coupe with AC power windows and power sun roof?

You need that gray rod and the linkage that fits on the end of the rod to make that motor work from what I understand. I hooked up my air/mix motor with the rod but I don't have the swing arm linkage to connect the rod to the lever that switches between the hot/cold so my system is incomplete right now. I read the instructions a hundred times and there was no mention of that other unit or the black box so I took it out but when I realized that I had no swing arm linkage I put it back. ?????????????

Argh that's what I thought I guess my setup is incomplete, I wonder if these guys had the full setup or you can make a custom rod + bracket to make this work? Maybe home depot?

So I guess i'm the only one with that black box eh? Hmmmm I'll look into this more and hopefully one of the succesfully people here will see this post again

[iiymij]

Bump looking for any pictures of the door mix motor installed with the metal gray rod? Does it need the track as well for it?

and do i need the black sensor here?

Hey guys I've got my DCC lit up and buttons all work on it but none of them do anything. I picked up a Blower Motor Sensor and Thermo Amp Sensor from a 90-93 Q45, but it looks to me like they won't work for this. ericherm1 used a Blower Motor Sensor with four wires coming out of it and it also looks like Beatupsx used a four pin one also.

Then I've also got this which looks like the Ambient Air Temp Sensor but isn't the same as the one Beatupsx used. The guy I bought it from gave it to me along with the DCC, so I'm guessing it should work. Did they make different Sensors?

[iiymij]

Thanks for keeping this thread alive from the first page of this thread the Blow Motor resistor sensor needs to be from a JDM clip in order for you to cycle through the 1 different speeds as for the rest I'm still figuring that out as well....

this might help

zer...r.jpg

is yours cycle through any of the speeds and is your temperature going up or down when you use it as well?

[MoldyOldy240]

alright I hope I am on the right track here. I've been wrestling with this for about 2 weeks now... wiring confuses me greatly.

Here are pictures of what I have done thus far. Please excuse the crappy quality.

I started with the harness for the dcc. I spliced in the red wire, I repositioned the green wire, and unplugged the blue cap.z



Then under the glove box I only did one thing; I swapped out the one bit...I don't know what its called, for the JDM piece off the clip I have.

and this is the end result:

it turns on... thats about it. It can engage the A/C unit, but nothing is blowing into my cabin. When I turn my lights on, the unit turns off for a second and then turns back on but is dimmer. I am sure I screwed something up and am missing a big step. I have a whole JDM wiring harness, but I don't know what I need to do next. If any ones knows, and can tell me, that would be sweet.~Nick

Above is original post.

I am a million times more confused now lols

[240_ESEX]

... the Blow Motor resistor sensor needs to be from a JDM clip in order for you to cycle through the 1 different speeds ...

Alright I misunderstood something on here then cause I thought you were able to use one off of a Maxima, and I figured the ones from a Maxima and Q45 were the same as long as they had a DCC.

My Unit lights, and all the buttons work, but it doesn't do any of the functions. My Mix Door Motor is also missing the Rod and Linkage. And it seems like thats nessecary to get that to work too right?

[iiymij]

wrong info first part

As for the different modes of blowing I think you need the JDM air mix door motor, as I think they call it. It should be the unit in this post just above with a gray steel rod. As for how to mount that piece I'm still kind of confused when I took out my USDM climate control. I'll try to add pictures later and see if anyone can help me out on that.

You must have the correct blower motor speed sensor. If your using the factory US blower motor sensor you will get the exact response as your getting now.

You can get the proper one from a Japanese clip, eBay, or 96 Maxima, and I heard that the digital control unit in the later model 300zx uses the same speed sensor and other sensors but not sure so if anybody wants to check it out to confirm this...please by all means.

actually i went through the entire thread again and you can use a JDM clip blower motor resistor or sensor from a 96 maxima

im offically confused once again

so I guess it doesn't have to be jdm... i was wrong argh sorry man im still learning how to do this as well

Alright, I thought I read that, but I took mine from a Q45 and only has three pins to it whereas the JDM one has four, and someone else had a three pinned one from an R33 that supposedly wasn't going to work. IDK, this whole thing is a pain, and its freakin cold at night and I have no heater to warm me up at night.

[charlie2020]

Heres what I've done so far to get started:

1) Disconnected stock USDM ACC blue relay2) Connected single red wire from DCC harness to the 3 wire connector on the USDM harness to the red/black stripe3) Re-pined green/white strip from 6 wire plug and insert it to the large white harness next to the green/yellow stripe wire

This is how far I have got so far and this is what works:

*It lights up but the red and blue lights dont light up*The Mix door motor works when I change the temp up and down.

to be continued.....

[iiymij]

Swt another member trying to make this happen. I'm going to try to put it together tomorrow and see if I can get it all to work although Im missing the motor resistor sensor thing but we'll see how it goes thanks Charlie for posting up what you got so far

[charlie2020]

Ok so far I have absolutely everything working so far minus control over the fan speed....

Couple of things I wanted to point out that absoluetly confused the *&^% out of me since for 2 main parts they happens to be more than one name for below i'll post a pic of teh part and there names:



On the right side of the cooling unit this part is known as the following:* Fan Control Amp* Resistor* Blower Control Amp

On the left side of the cooling unit this part is known as the following:* Thermo Control Amp* Thermistor

Also here is anotehr pic from the FSM:

Here are a few more pictures I think are helpful in naming and describing parts, locations that pertain to these thread:



NOTE: Not all S13 have the relay on the right of the above pic (Max. Cold Relay) but they should have teh blower relay.





Here a JDM Nissan FAST screen shot of the Digital Climate Control and few other sensors and a wiring harness pic:

Also thought this would be a good pic for peole to see how the analoge air mix door lever hooked up to the stock control unit box:



I unhooked everything in the pic shown above BTW.

It is very easy to hook up the JDM mix door motor it required me absolutley no cutting or bending the only thing I did was to unclip the rod and squeeze together and press out the yellow tab and reverse it and put the steel lever rod back threw the hole provided and them mount the lever arm with JDM metal clip that mounts to the rod with a phillips screw pictured above and that was all.....but I will note that the JDM rod is to short for the climate control to move threw it entire range of motion.



Here is a pic of the other control rod on the other side of teh control unit box that you can use to modify the JDM control rod but make this one about 1/2" longer (this is helpful to you only if you have the JDM control box to use this part:

wow that is great info how'd you get a fsm that showed all of that cuz mine doesnt? and is that a program for all the car parts? let me know if I can get my hands on that

I'm having trouble putting together my max cold door motor (m73) , my analogue is just a white tube and a gray wire inside and for the life of me I can move the max cold relay (m71)

Do you have a Nissan FSM? Becasue if its a Haynes or Chilton theres a good chance it might not show everything. Yes I can see all USDM parts on teh FAST program and most of all JDM parts to, the important ones here mainly PS13 SILVIA and RPS13 SILVIA....

What do you mean by trouble putting together max cold door motor??? Im confused becasue my 91 S13 did not have a max cold door motor (M73) it just had the tempature control cable also did not have the max cold relay (M71).

If you installing the S13 JDM Digital Climate Control as far as I know you wouldn't need the max cold door motor and max cold relay anymore but you definantly need the hot/cold mix door motor and the blower relay (M64).

[charlie2020]

Here another good resourse with lots of pis and details its for an Altima but still has useful info and pics...

Got a havac motor and plugged it up. The first time I turned on the DCC the havac motor moved but it has not moved again since then. I move the temp all the way up and down but the havac motor has not motioned since the first time. Anybody solved this problem? Anybody got one of those clips that go on the end of the havac motor swing arm for sale?

Modified by positronone at 3:16 PM 12/3/2006

The reason for the hot/cold mix door motor not moving is becasue you must have the cabin temp sensor pluged in and the mix door motor must be the JDM one.

[charlie2020]

actually i went through the entire thread again and you can use a JDM clip blower motor resistor or sensor from a 96 maxima

im offically confused once again

so I guess it doesn't have to be jdm... i was wrong argh sorry man im still learning how to do this as well

As far as I can tell from looking at all teh Nissan/Infiniti USDM FSM's all Nissan and Infiniti Fan Control Amp AKA Resistor AKA Blower Control Amp are all 3 wire units so it definantly looks like you must use a JDM Fan Control Amp AKA Resistor AKA Blower Control Amp.......unless someone can prove this false please do and show me a 4 wire Fan Control Amp AKA Resistor AKA Blower Control Amp from a USDM vehicle or show me how you made the 3 wire work....

[charlie2020]

Since there seems to be no available S13 SILVIA FSM I got this from a S14 SILVIA SR20DET FSM:

RHD Manual

LHD Manual

Note: The S14 Manual Climate control does in fact use 4 wires for its Fan Control Amp AKA Resistor AKA Blower Control Amp pictured above (M52).



Note: The S14 Auto Climate Control does only use 3 wires for its Fan Control Amp AKA Resistor AKA Blower Control Amp pictured above (M50).

I mounted the havac motor but I think that I am missing something because there is no way to connect the swing arm to the lever that actually opens the door. Anybody got pics or milk?

You need this part heres a pic of how I did mine, btw this is the JDM rod, I reveresd teh yellow plastic piece basically fliped everything around that way it would mount to the shaft and then your able to secure it with teh lil phillps screw:



and this is how I mounted mines:

I just need one of those type washers like the ones used to hold on a bicycle rim to the forks with the little hook on the washer for this location below in the pic:

[iiymij]

those are some great install pix and I am saving this page, really appreciate it Charlie, I was having a hard time hunting down these parts just wondering if you would know where to get the blow motor resistor and that arm link? I think I've got it powered up but since Im missing those 2 pieces my DCC doesn't do much right now

[positron1]

Good luck, I've been hunting the swing arm linkage for some time now....nothing!

[charlie2020]

You guys don't need any particular swing arm you just need one thats longer than the JDM swing arm, I modified a longer one with a lil bit enginuity, a torch and a hammer modify a swing arm to work for you its really easy.....what needs to be done so you get the full range of motion is line up the mix door motor swing arm with the cooling unit pivoting arm so that they are as close to parrallel with eachother as possible for best results......
