Why does the heater overheat to over 100 degrees and the air conditioning not cool? My car has been back at the dealership for 5 weeks and no repair done. Says it's normal??? No!
In my jeep the heater gets to 145 degree air out the ducts, switch it to full A/C and the temps drop to 38 degrees. It sounds like a blend door is stuck. It is a big job to fix it so maybe they are trying to just shove you away, you might have to go to another dealer.
