Air Conditioner Problems (stuck on econ)
I have a 1992 SSE with and electronic climate control and I can get it to switch off of econ over to auto for the air conditioner. I just got this car and it was working perfectly for a couple days. I did a few repairs which may have affected the A/C without me knowing. They were changing to a 180 thermostat (which I had to disconnect the battery for) and I opened up my airbox then removed my MAF screen (which I have since put back in). I dont remember if the a/c worked right after I did this, but now it doesnt work at all. When I start the car the temperature flashes for a while and it is always on econ. I can control everything else, but I cant switch it to A/C. I know I dont need a recharge because I took it to the shop a week ago, but that was before this.

The blinking means there is a ECC (Electronic Climate Control) trouble code. Look in techinfo for the procedure to get the codes. Then let us know what it gives you.

I got a code number 48 which means long term frion loss. Is there any way I can fix this myself or do I have to take it in.

Leaks are hard to find without some form of dye in the froen. And if it's a slow leak, like "long term" suggests, then it makes it even more difficult. The leak may be easy to fix, depending on where it is, but might be difficult to find. IMO, shops tend to overcharge a little for this kind of stuff, but it may save you a lot of frustration.

Clear the code, and go about your life. Mine has done this 3 times in 2 years, and the AC is still Ice-cold. Consider it a bug, unless you lose your cool.
Use the procedure in Techinfo to clear the codes VERY carefully. Step-by-step. |
I did clear the code, but it is still not cool. I dont understand it because it was ice cold a few days ago. I disconnected the battery to see if i could reset it somehow and now it has error code 52 or 152 - Keep Alive Memory lost; sets with battery disconnected and 40 or 140 - Driver Air Mix Motor circuit open or shorted, or not calibrated. Can anyone help with my wacky A/C.

Does the 180 thermostat that I installed have anything to do with my air conditioner issues?

Does anyone think my error 140 is the problem - Driver Air Mix Motor circuit open or shorted, or not calibrated. Can anyone tell me how to fix that?
