If it is smell like rubber, that means maybe the electric wire too hot and some places short. be sure to check it.

This situation sometimes caused blow up fuse.

SOURCE: Blower does not work on my 2006 Chevy Silverado truck

I had this same problem. What I did to resolve it was to slap the underside of the fan housing (in the passenger floor board) until the blower came back on. The fan/blower housing is that big black box right under the glove compartment. I know that sounds stupid, but I think there is a plug above the blower that is not making a good connection, so when I slapped it upwards it reseated itself and the blower came back on.

SOURCE: No Heat and Overheating in 1999 Chevy Silverado

After replacing the thermostat, you must bleed the air from the cooling system.

To bleed air from the 2.2L and 2.5L engines, remove the plug or sensor on the top of the thermostat housing. Fill the radiator with coolant until the coolant comes out the hole. Since the plug is made out of steel and the thermostat housing is aluminum, it is a good idea to apply an anti-seizing compound or Teflon® tape on the plug threads prior to installation. Install the plug and continue to fill the radiator. This will vent all trapped air from the engine.

Any trapped air in the heating system will have to be displaced by coolant. Once the cooling system is filled, with the radiator cap off, turn of the heater at it's highest setting. Start the engine and allow it to reach operating temp. You should see a drop in the coolant level as the air in the heating system is displaced by coolant. Add coolant to the proper level and replace the radiator cap.

Keep a close eye on the coolant level for at least the next couple of weeks. The cooling system is a "closed" system. Any significant decrease in coolant level indicates a problem.

If you have any questions, let me know.

Please take the time to rate this solution.

Drive safe and be warm.

Why doesn't the heat come on in my 2005 Chevy Silverado heat unless engine is running above 1200rpm ?


educated guess is that you have an air lock in the cooling system and the heat is only apparent when the high rpms push the water into the heater core
find the highest point a undo the hose and let any air out ( cool engine only as the water may be hot)

2004 chevy k2500 no air out of defrost vents, temp controls work fine cannot direct air to defrost vent


You may have a problem or bad connection in the a/c-heat control unit I'd remove that and inspect that first. As long as you do have heat elsewhere you can rule out the blend door actuator. There are vents that open and close and you will need to be able to access and check them. You will need to remove dash to be able to get to them.

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.

Is the correct name for the part that controls the air flow from a/c to defrost called the A/C Heating Servo Unit, the defrost does not completely defrost the front windshield but the a/c works just f


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.

most american cars force the defroster to blow cold air, this is not a problem, it does this by design.
