01 ML320-I SCEWED UP
As soon as I unplugged the harness for the switch, the AC started blowing warm air. I installed the new switch, put everything back together and checked the fuses which were all good. Aside from being an idiot and doing this with the engine running, What did I do? I didn't think this switch has anything to do with the AC system. Your help is very much appreciated. Its supposed to be 107 on Saturday.
