Turning the temperature control dial on the console has no affect on cabin air temperature. Fresh/recirculate doesn't matter. Once the engine warms up, the airflow it's always HOT. Tried running the AC but that is hot as well. This problem just started a few weeks ago after a "routine" oil change at the dealer (hmmm). Engine coolant temperature normal, not overheating at all. About 62K miles... I'm stumped. Is there a sensor gone wrong here?
Any ideas? Thanks in advance...
