Question about 2004 Chevrolet Silverado 1500 Crew Cab

1 Answer

The blend or defrost will not work on my 2004 Silverado stepside 1500. A/C and heat controls work fine. The unit just will not turn the air to blow out the floor or the defrost.

The blend doors are controlled by small electric motors.

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.

Chanses are its either the blend door motor quit working or the controls ( temp., selector, blower) in dash are bad, my 95 did the same thing i chg. the blend door motor thinking it was that, but it turned out to be the controls in the dash, 5 minutes work and 140.00 later it was fixed.

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.

Sounds like the blend door in the ducting has failed, this door is what controls the temp of the outlet air by blending heat and outside air or AC cooled air.
