Could you tell me where this cabin temperature sinsor with its own fan is located? I think I know where 2 are above the driver and passengers grab hold by the upper part of the doors. How do you pop these little guys out? I re-took the codes, all cleared by 419. Same old same old, turn key on, fan comes on for 5-10 seconds, then off. I have no control even in manual. I took car on 5 mile drive and got it warmed up but that didn't matter either. I took some contact cleaner and sprayed around controls on the ECC but no luck. I mailed off some money for a working ECC from a guy in Wisconsin, so now I have to wait further and hope that is it. Man, this gets frustrating. Thanks for responding to this thread too!
