95-850T 136K Last week none of the ECC worked at all. No blower, no AC, no heat, no defrost not on any setting. I cleaned out the dust balls from the sensors over the front windows and immediately the everything worked. Now,the AC only functions when the cabin gets hot...so to get cool you need to heat up the cabin with open windows!!!???

I did not check or clear codes after I cleaned out the dust bunnies. Is that the problem or???

I roll down my windows because that is the only AC that I have :>)

You could check your codes again, the cabin temp sensor errors should have gone away.

What temperature are your dials set at. Pick a comfortable number and leave the dials alone. The AC and recirc switch should both be green, the fan on auto, and vent selection on auto.

Thanks Klaus...the AC and recirc switches have always been yellow...or maybe they are dirty! I will test the car with me driving it and not my son's report.
