Why would a Pontiac Sunbird only blow cold air when the heater is on and the temperature gauge run super hot but the car does not overheat?
It sounds to me like the heater core is out. Have you noticed the floor wet recently? that's a sure sign of heater core issues. The other option is it will act like that if it has no antifreeze or water in the radiator, in other words the radiator is dry.
Just a suggestion if someone has replaced the thermostat its possible they installed it pointing in the wrong direction this could account for cold air and the guage reading over hot. , EzForJesus
