Heater problem
1984 Cadillac Cimarron 4 cyl Two Wheel Drive Automatic

Last winter the heat only worked in the hottest position on the controller. The fan works in all speeds as well as the air conditioning and damper (Def, Heat, Vent). This winter the heater is not working at all. I just replaced the thermostat but still no heat. Where do I turn next?

See if you coolant system is full first if it' s not you won't get any heat. If not you r heater core could be partially blocked and you would need to disconnect one of the hoses and flush it backwards. But doing this on a car this old will probably break it.

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
