Hey Crazy,
Pull out the glove box interior. About 6 screws hold it in. You will see a threaded rod. Turn the car on and set the temp. up to about 90. Look at the position of the rod. Then change the temp. to 65. You should see the rod travel about 4 to 5 inchs as it closes the door to cut off the water flow through the heater core. Then change the temp. back and it should change again. The gear you are talking about is on the back end of this rod. Hope this helps.

My heat in my 2006 trailblazer wont get hot


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.

On my 2001 windstar when i turn the lever to hot section I could hear click, click sound and it does not get warm only cold air coming.


Global 1207 is right. It's your blend door actuator which is sticking. Probably the plastic teeth on the cog inside are worn. It is white plastic and is located behind your radio. It controls the opening of your blend door from A/C (closed) to heat (open). Buy a Ford Windstar radio removal tool from any parts store (less than $10.00) remove the radio. You will then have access to the actuator. At the bottom right you will see a little plastic wheel with an indented square. Find a long flat head screwdriver that wil fit diagonally into the square and turn it clockwise slowly. The blend door should pop open and heat will enter the cabin. Finally when you have the time replace the unit. They sell for about $75.00 at the dealer or cheaper elsewhere. Good luck. This worked for me.

Not sure if you still need an answer, but the air mix door is likely not opening and closing properly. This is attached to the temperature control knob on your dash and is what selects hot or cold air to enter the cabin. The cable connects just above the accelerator pedal and you should see a cable, attached to a black gear that turns a white gear. Sometimes the white gear becomes loose and falls out. Nissan Technical Service Bulletin on this. If you remove screw holding black gear and turn white gear it should change your temperature. The TSB is easy to have Nissan fix or you can likely perform.

Caravan air filter


The air filter for the cabin is located inside the van, look under the glove box door there should be a plastic holder that slides to the rearward of the van pull this back and a flat plastic door will come off, the door is two parts.

Some base vans do not have this filter if you look at the bottom of this and see a 1/2 long plastic stud sticking out of the bottom there is no filter in this.
