Might want to back flush the heater core, there might be sediment build up thats restricting the flow of coolant thru it.

1994 silverado heat is not working. Replaced thermastat, heater core and checked fuses. Still no heat. The blower motor (high, med, low, is working fine.


I think that one still uses cables to control the blend doors and vent doors. Are you sure those are working and/or connected.

Also when you replaced the thermostat and heater core did you bleed the cooling system? With the engine cold remove the radiator cap and let engine idle up to operating temp while keeping the radiator topped off with coolant.

Are the hoses going to the heater core hot?

Well it would be the "mode door GM pt#88986538" or the "mode control cam actuator GM pt#89023358" on the side of the heater case. The door would control where the air comes out and the actuator tells the door where the setting is at on the control head.
