Anyone at all know anything about the heater system on a 92
I own a 92 Bonneville SE that Doesnt have electronic climate control. My problem is, I will have the Ac on it'* nice and cold, But when i need it on heat at night i go to turn it to hot and defrost and It will still blow cold. I can turn the **** to floor heat and it is still blowing cold. Hell at times i turn it completely OFF and i still feel the cold air on the floor. Sometimes it will take days for the damn thing to work. Then of course when i need the AC to blow cold again, it will still be stuck on heat.
Anyone have any thoughts on this. I replaced the control panel and that wasnt it.
