Ughs, I tried the different ones on the stereo, ie plain blue wire, blue and red no go there, and my black and red wire doesnt seem to be working anymore because my DCC doesn't remeber my last settings. Checked a few fuses and nothing...

i hope it gets better from here on in, anybody have any ideas?

could my blower motor sensor be blown?

To anyone having blower motor problems, I figured out the problem that everyone is having. I had the same problem when I installed mine. It also makes sense why some have issue and others do not.

Problem:

The JDM blower speed controller is deeper than the USDM one. The bottom 2 fins on the JDM unit hit the Aluminum AC line inside the blower box when you bolt it in. This grounds the chassis of the blower speed controller which causes it to run the blower motor at full speed. If you unbolt the blower speed controller while the blower is on and pull it out just a little, the blower motor will stop running at full blast and run at the speed you have it set at. This is just to test to see if the grounding problem is indeed your problem. If so, just grind down the fins a little and problem solved. Some people don't have this problem because the AC line inside the blower box is bent slightly different than others, effectively giving more clearance and not grounding out. I also had to have both the blue USDM high speed fan relay and the JDM relay plugged in to get the speeds to work correctly.

I never really thought about it.

I'll try to think of something, but if I haven't come up with anything in a week you can just suprise me with something.

It shouldn't cost more than $200(I've seen complete setups for around $150), but I have around $100 in everything so it is very easy to do for considerably less than $200.

Hey guys....I followed the intructions carefully and my unit is acting weird. When the ign is on the blower is working but is uncontrollable and the Digital unit flashes on when i press the fan button but then suddenly turns off......And the oddest thing is that the blower will work without the digital unit being pluged in....and when I unplug the blue relay on the harness it goes off. Can anyone help solve my problem? thanks.

Okay I moved my harness around the other day and now my blower won't seem to work....the resistor is out of the box so no bad grounding...soldered all connections and so no loose wires. I also cannot circulate through the vents. Is it a bad motor or something.....all the fuses are intact and blower work when connected straight to battery. Please help.

i have a similar problem but for me still no go blows hard as well

to make it simple ill just write out my steps again

1. took out the green white wire 7 pin JDM plug and placed into the 16 pin JDM plug to be connected

2. ground the red yellow wire from the USDM side going to the car to my shifter

3. have the blue red wire from the 7 pin JDM plug to my blow via this wiring method



*1 - to OEM blower plug (b/r)*2 - to 7 pin b/r wire *3 - to oem blower plug (b/w)

4. straight plugged in my USDM plug for the blower resistor motor sensor into this blower motor sensor



5. plugged in my USDM and JDM fan relay

6. connected plugs and blows hard no way of turning it off

side notesthe blower resistor is not the one with fins, its the one kevin supplied me

ive tried plugging in just the JDM fan relay, no goive tried plugging in just the USDM fan relay, no gotried both plugged in still no goi've pulled out my blower motor resistor from the box and if it doesnt touch the AC pipe it doesnt blow at all

if it touches the AC pipe it blows like no tomorrow

i think its the blower motor resistor but until then, im at a stump

it took me somewhere around 3hours to finish completely, mix door motor was the worst part. but over all it was pretty simple (but i have electrical background)If you follow zerothread?id=5142 and only this write up, i tryed a few others but only this one will work on a US 240sxjust follow it step by step and you'll get through.



good luck

no you don't 'need' the ambient temperature sensor hooked up, its only for the auto function, when going through the dignostic mode to check on all sensors after install, in test 2 you will receive an error 21 which means theres an issure with your ambient temp, also in test 5 you will read -22C as your ambient temp, this means your sensor is not present or is not working. either way everything works fine without it, except of course 'auto'

For those of you with a fully installed & functioning DCC, when you set it to AUTO, does your Fan blow at full speed?

Ok everyone just woundering because it seems confusing.

I just bought a climate control for $25 on ebay no pig tail or anything. I assumed you could just find another pig tail to fit but lets say thats impossible then I'll just solider directly and put some silicone in back then its better (in a way that I'll never be able to unplug it) then it ever was to begin with. I'd prefer a pig tail of course but from what I've seen so far that much I'm screwed on.

So besides that whats a list of things I could find from maximas, altimas, Qs and Js to help me out. it'll probably be easier once I have the part in hand. and that wire diagram ain't too hard to figure out.

I just kinda like to know how I could make it work on only USDM parts.

O and when I say a complete list a parts pics would help out actually just a pile of the parts I would need and what to look for.

If not I'll try to make a list once I get around to figuring it all out and doing it and post it up with pics and all. Its not impossible.

Take a good picture of the back of the DCC and post it up. I got some plugs that might fit. Please don't do the silicone idea, it sounds terrible!!
