i have a 2002 seville and the heater will not stop throwing off hot air regardless of whatever settings i imput. any idea's? also ac does not blow cold air. everything is hot.
The temperature control is gained by a electric motor that opens a heater core bypass door. When you want cooler air, the door opens. That would make your A/C hot too. Check your fuses.
thank you for your info. i will check out fuses. would they be in the bcm or the ecm? thanks again.
No fuses are in the BCM or ECU. They should be in one of the fuse boxes.
