I have an issue on a 2003 8 MR. The A/C and recirculation buttons are stuck ON. When I turn the key the recirculation button comes ON, and when I rotate the fan speed knob the A/C comes ON, and I cannot shut off both. The defrost button work flawlessly, and also everything else.
Ideas? I have tried to disconnect and reconnect the electrical cables from behind but nothing changes, and I cannot figure a solution on the repair manual.

 

is the temp knob set to "MAX AC"??

 

most likely

 

its this

been there, done that.

 

Probably, it's not my car and the HVAC cover has been replaced with a carbon fiber one that have no "legend "on it
I'll try later to turn the heat knob

 

Yes, it is the temp knob

 

At the Dairy Queen I put a malt on the dash and when I pulled forward it toppled over. Next day the emergency flasher button quit working and two of the A/C buttons barely worked. A spilled soda will do the same thing. Cleaning or replacing the switches is the fix.

 

Good to hear. I learned that lesson when I thought my buttons were broken the day after I bought my car.

 

Also, EUDM evos haven't the "MAX A/C" button, this one is an imported 8 MR...
