The heat in my PT Cruiser will not shut off. It’s not the engine overheating, it’s the interior air. It blows nothing but but hot air, no matter what. In fact, it doesn’t stop blowing hot air, even when the fan is (allegedly) turned off. What’s up with that?
Your car has an air door that directs the warm air inside the cabin when needed. When the heat is off it should direct cold air in.
So this mechanism is not functioning. A competent A/C shop can diagnose this quickly an fix it so everything is back to normal.
The temperature control cable may be broken or disconnected.
