Air Temperature Control Blend Door Failure No Heat or no AC (dependes on where door sticks)

In all modern cars there is a tiny DC electric motor driven gear drive that moves a plastic door that blends heated and cooled air from the AC and the heater core, this is called (interestedly enough) the air temperature control blend door actuator. The motor that moves this door fails because the door starts sticking from warping, most common complaint is no heat but it can be no AC as well. To replace these parts (blend door and blend door actuator) you must remove the entire dash from the car. Always have this problem confirmed by a dealer or qualified repair shop as it is a very expensive repair.

Other causes of no heat in the cabin are engine thermostats that are stuck open (engine runs cold) or air bubbles in the cooling system.

If the heater hoses are getting hot, the problem may be a faulty blend door under the dash. The blend doors direct air thru the heater core and the vents.

prob the blend door actuator or a vacuum leak

The blend door is not working right or the in car air temperature sensor is faulty.

This sounds like it could be 1 or 2 different problems. The first is the control head. Obviously if the control head is malfunctioning it is not sending the proper signals to the the blend door. If the control head is ok, then it could be the blend door itself or possibly the actuator. Unfortunately, you may have to remove the whole dash to get at the actuator or blend door

The passenger side blend door is not actuating correctly possible due to a vacuum motor not being connected up properly behind the console behind the dash board. Or, a bad blend door assembly.

It is a actuator motor on the inside of the dash ,mounted on the blower box,the dash will have to be removed to replace it.The actuator motor controls the temp door,and it is not moving the temp door.If this was helpful,at all,please rate,and thank you.

very lenghty process. too long to describe here....go to Bonneville Forums read the text and follow linked there at the bottom....very good and detailed....I'm doing that right now,,,,it is a bugger,
