As usual, i started the car this morning and it idled normally---AC still did not work. I popped the hood and after it idles for about 2 minutes the Aux fan came on before the temp. gauge even began to register. I pulled the 2 prong connector from the 105C-115C switch on top of the thermostat housing and the aux fan stopped and the AC compressor came on.
I replaced it and pulled the single prong connector on the same switch and the Aux fan continued but the AC compressor came on.
Could this be the problem with the high idle also?? I always suspected that something was telling the car that it was too hot, and could have caused a high idle situation---but the AC always worked until today, but i was always at high speed on hte interstate. I think i will change out the Aux fan switch---i guess the other prong is going to the computer to tell it that something is hot.....would this be a correct assumption??? i hope this is hte fix--its must better than the ICU solution!!! I'll keep you posted. Thanks
