SOURCE: Problem with AC, dual climate zones

The temperature blend door on the driver's side might be broken or stuck. Also, if this vehicle does not have the correct amount of refrigerant, it will do what you are describing.

I had the same problem. Took it to an AC guy and they told me it was going to cost $1,400 to replace all kinds of parts. I didn't get it done right away because I went on vacation. When I got back from vacation the air blows cold. It hasn't gone back to blowing hot since.

SOURCE: Cold AC but weak Airflow---Also Driver side not as cold as passenger

The air doors are controlled by actuators that on of them or so may need replacing.

My 2011 dodge durango citadel has cold air blowing on drivers side AC and warm to hot on passenger side ac


Dual air. The actuator is bad. It is between the fire wall and HVAC plenum. The dash has to be removed along with the plenum. Costly job at the garage.

The ac is blowing cold on the passenger's side and warm on the driver's side. What's wrong. The rear AC is working fine.


either a module for the climate control is bad or,one of the little acuator motors to open vents is bad

AC unit is blowing both cold and warm mixing as if


Sounds to me like you've got a stuck door. One of the doors in the air ducts isn't closing/opening all the way. Possibly stuck or possibly a vacuum leak or disconnected/broken vacuum hose. Only way to know is to pull the dash apart. Sucks but gotta be done.

2003 buick lesabre AC problem


You have to find the motor that controls the blend door and open it manually to find out which one is bad there are 3 blend doors on the HV/AC system one will be where the heater core is. The other will be between the vented air and AC? heating system then the third door will operate vents in dash and defrost condition. If you have someone operate them AC system heating system and watch the blend door motors, the one you find not moving will be the one that has the problem. They have vacuum and electrical motors, if it is a acuum motor you can move the door manually with your hand, if it's electric you will have to disconnect the rod by removing the pinch clip off of the rod.

2001 buick lesabre-ac problems


  • Assumed your AC unit is OK, but uneven temperature distribution. Try to throw the heater on an off severtime. A sticky valve on the heater would cause similar problem.
  • Observe the RPM while parking your car. While the AC cut in cut out (or turn on an off). If it cause no load on the engine. The freon may be low or the compressor is bad. In this case only the intake side of the evaporator is cooler than the other side.
