My heater worked a little bit today when I had the thermostat changed but notice the fan wasn't working and that's why it did not heat the cabin. Now I notice the air compressor is coming on while the


well the ac compressor will come on if you have it in defrost mode,if heater is blowing cold ,after you just had thermostat replace ,you could possibly have air in system.now if your heater motor is not working which is called the blower motor under dash it could be the resistor that controls it also these rigs have been known for wire harness problems at heater control unit and the blower motor connector.good luck,mike

My is heat is not work?My car is blowing cold air instead of hot air, I have a brand new heater core,the thermostat is not sticking,I got anti-freeze in it,It's getting cold in I need heat.Please help me


first feel the heater core hoses see if both are hot if so then your problem is in the blend air door must be stuck on cold. is your blower motor blowing cold air if not your blower motor might be the problem. the blend air door is down by the blower motor.

1995 Chevy k1500 heater problems.


For a 95 Chevy Silverado....I replaced the Blend Door Actuator on the passenger side. Just behind the slide out cup holder. Yo ucan acces easily by removing the ash tray piece and the glove box....Or just the glove box and work like hell to get a socket in a tight place.

There are 2 actuators....one controlling the (Mode and Temp 89018681) and the other the (Air Inlet 89018367). I called the dealer and the parts were 85-125. I got it From TBA Auto (local store) for 39.00. A 20 min job at most.

It sounds like you have a blend air door stuck. This is in the housing of the heater a/c blower unit under the passenger side of the dash. There is a motor on the top of the housing that could possibly be stuck or on working.

Blower motor location and installation on 73 ford gran torino


It's less than foot from the heater core. I would guess that either the damper doors are not on correctly or the vent hoses are not hooked up. Can you hear the blower motor running? Maybe they didn't hook the motor back up when they replaced the heater core. It takes a ground and a hot wire.I can't remember where it's at but it may be part of the same unit. Did you check the fuse?
