ok i searched but came up with stuff about the jdm climate control. anyways heres my problem. my cc doesnt blow air/heat anymore. i remember from readin about it a while ago that its common for the solderings to break on the board. fine im sure ill be able to fix that...but how the hell do i get the ****** out?

awesome man...thanks bro

now i have somthin to do this weekend haha

 

ok i did wut the writeup said to do. didnt work. so i went a lil more in depth to see where else the problem could be. obviously started with the fuses...all good there. used the circuit tester tool with the lightbulb n did some testing with that. the green harness to the climate control lit the bulb so that had power. i checked the brown harness n that had nothing. so im thinking could there be somthin wrong with the wiring? any1 have any other ideas? im no wheres near an electrical engineer or anythin like that so i have no idea im stumped.

 

i've got my old usdm unit for sale, if you can't figure it out

i would assume it's the unit of the harness has power.......maybe go double check the solder points

 

its not the unit itself... i just resoldered everything. the panel has power as i already stated. its the brown harness that attatches to the switch thats not reading any power

 

any1?

sorry i stopped reading mid paragraph when you said the first one had power......i'll check later on and see if i can remember where everything runs from that harness.....i made a few notes when i did the jdm conversion

does the unit light up or anything?

 

yea everything works...lights, buttons, rear defroster. the temp control even works when im driving n air comes threw, it will be wut the temp control is set on. the only thing that doesnt work is the fan switch. now obviously u would think its the switch thats not workin. but if it was just the switch then there would be power comin from that harness. theres no power comin from the brown harness that gets clipped into the switch.

 

any ideas guys?

 

cmon ive read so many threads about climate controls goin bad n a simple resoldering fixed it. unfortunately this isnt my case. no one has ever heard of anythin like this?

 

First get a helms or I have a pdf of just the wiring diagram.
If the switch was bad then it would get power from one harnes and then send that through the switch to the motor. If you are saying you get no power from the switch and there is power going to it that would lead me toward the switch. Since you have no power then you need to check the AC switch. You'll see that is next on the diagram.

Have you tested the green wire (position 1) on the switch harness the same wire is green (position 2) on the main unit harness? The unit needs to be on. If that dosen't have power then look to see if turning on the AC does anything. That's the circit green gets power from.

At that point I can't really help you because I don't know what the board looks like, but there is a diaode before the AC then you get into the actual switches (rec. vent, bi-level, ect. )

I think somewhere in there you'll find your problem.

Maybe we need to get Mgags in here to tell you I'm wrong, but since you seem alittle worked up I gave it a shot.
Good Luck

ok heres wuts up...the green socket that is "supposed" to be the problem wasnt the problem. that was resoldered, n the harness that plugs into that works fine. the unit as a whole has power. everything is lit up. my rear defroster works, the air circulator button works(u can hear the door open/close), the a/c button works(u can here the fan come on), all of the vent switches work bc while driving air will seep in through the vents n it will come through wutever vent button is activated. the hot/cold slider works too.

the reason i dont think its the switch is bc i checked every wire that is in the brown harness that gets plugged into the switch n none of those wires has power comin to it. of course i would like to get another switch to validat that though, which i plan on doin asap.

now when this 1st started happening the blower would work n then it would fluctuate a lil bit n then it would stop blowin air. somtimes it would stay on. sometimes it would come right on n not last long, somtimes it would take time to start up but then stay on once it started. now from all of the threads i read while searching would basically say that those things r the prime examples of that green socket needing to be resoldered. of course this is my car n its never that simple lol.

so back to the brown harness not having any power...this either leads me to believe that theres either somthing wrong in the wireing, or maybe the motor is shot n thats y its not blowin any air.

**on a side note i would definately appreciate that pdf of the wiring diagram that would help out immencely**

 

re-read my post. It wrote it quickly. The brown harness that goes to the switch has a green wire in it. That is the wire that needs power. That loops back around to the main unit still a green wire. So the switch gets power from the main unit only when the main unit is on. The board takes it from here.

 

ok ill double check that thanks again mat
