The electronic door actuator on the drivers side has gone bad. It's common on the gm's and dodge since there very similar in parts and think that come from the same supplier. There is a electric motor with worm gears that crack and the door no longer moves to open or close to adjust for the temperature coming out of the vents. You have two of them, one on the passenger side and the other. You guest it on the drivers side which i believe is the harder one to get to. You may be lucky and it may be just a wire harness that may have gone loose, but i doubt that. Best thing to do is go to Auto Zone and have them check for a DTC code and if there is nothing. asked them for a step by step instruction to replacing the part you need and have them price it. It will be cheaper then the dealer or if you like after you get the instructions. You can go to the salvage yard and find one still in a car like yours so you know how hard it's going to be to replace it and the price will be average if you remove is like $25.00 with a 90 warranty. Good luck and keep me posted.

check the actuator motor and make sure it is moving the doors between the heater and the ac. it is in the center of the heater inside the car and is a small motor attached to the heater housing.

I have a 2004 Monte Carlo and My driver side blows out cold air and my passager side has heat. why dont my driver side have heat???????


you have "blend doors" under the dash, most likely you have dual side temp controls, and the little electric blend door actuator is bad, they are not easy to get to, but can be done in the drive way, hope this helps,

2003 monte carlo a/c works of and on,already put freon in twice and the security light omes on and also the traction active light comes on


Re the a/c. Get a can of red tek sealer. make sure the engine is cold or you won't get the connector on to the low side port to seal properly. Follow the insrtuctions that comes with the can. Just adding the refrigerant doesn't stop the leak

Can't find the fuse box for a 96 Monte Carlo


The fuse box is located on the passenger side panel of the dash . you have to open the passanger door to get at it.

The other fuse boxes are under the hood, on each side under a diagonal support arm that has to be removed to get at the fuses & relays
