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.

Blend door actuator failure is a common occurrence on many older Explorers. The clicking noise is actually caused by a stripped nylon gear constantly attempting to hold open the blend door which mixes the hot and cold air sent to registers on dash. As long as the temperature control setting is in the heat range this actuator will hold the door which wants to be normally closed, open. Air flow when the fan is on helps to hold the door open relieving stress on the gear. However whenever the fan or engine are off and the temp control is in the heat range the small gear must hold the door on its own which eventually leads to failure. A tip is to always return the temperature control to the cooling position whenever heat is not needed or truck is turned off. If you are reading this too late the link below will provide you with step by step instructions to replace actuator. I would recommend an OEM replacement part, it makes it easier to orientate when installing the new one. Did this myself and all went well.

The sliding switch on the console is stuck in the cold position and the knob is pulled off. Use pliers to jiggle the switch as best you can. Feel under the center console and you probably will find the cable that is hooked up to the flapper. You'll know because when you jiggle the cold/heater switch at the upper console, the cable will move slightly. At the hookup of the cable to the flapper down under the console (passenger side) try to work the flapper loose to the open (or close) position. At the same time work the sliding switch (with pliers). The flapper will come loose and function properly. Try not to knock of the AC button like I did in the process. It flew off some where under the passenger seat. I'll find it sometime before summer. Ha.

Your Actuators are not working on the front compartment. They are dual doors that open when the demand for heat or AC are pressed. Yours are either stuck or just plain worn out.

My ac it's working bad, non cold air. I notice the air it's coming out from the top of the panel and from the bottom, looks like the switch stuck, so I can't swich positions to see if the ac is working....


1st thing you can check is to open the hood and have a helper turn the AC switch on and off and listen for a clicking noise from the engine compartment. If you hear this clicking noise everytime the AC is turned off and on then it is likely the AC compressor is working okay which would likely mean your blend door and actuator is stuck or has malfunctioned somehow. In either case they are both jobs for skilled tech's do to the likelyness of having to remove the IP to change them. If you do not hear any clicking noise under the hood then check all fuses and if they are all okay then I would recommend taking your car to a local tech that is AC certified do to the complexity of an AC system. Hope this helps.

Shifter stuck and key will not come out of ignition


yes, there is a light and they may have just forgotten to plug it back in, it should be accessible from the small compartment next to the gear shift, if not, remove the surrounding console and you should be able to find it. there should be 2 lights in there. 1 for the small compartment and another for the gear shift. if it is plugged in check the globe to see if its blown. as for the "little shift interlock mechanism" i would suggest taking it back to the shop and asking them to make sure everything was fastened and tell them you can hear it rattling around. you never know, it may be the wires and plug for your gear shift light.

2002 mitsubishi heater not working


I just spent my whole day with the same problem and it looks as if alot of other people have too. You need to replace the control valve. Take your glove box out, then take your center console peice out. Then you have to take the passenger side plastic off. This is the peice that surrounds the glove box. Once you have done this if you look underneath the dash towards the center console you will see a little box with an arm on it that goes down to an aluminium hose. That little box with the arm is the control valve.
