Hello. My 05 Lesabre has cold air blowing from the upper vent on the passenger side the but the drivers side is warmer air is this a actuator problem? I have located 2 actuators but they seem to be working fine, there must be another one that controls the drivers side vent heat/cold? thanks guys

 

Hi Rick,
You will probably need to remove the glove box in order to see what is going on behind it. Not that difficult to do, but practically impossible to see any other way.
Let us know what you find, thanks.

 

I have already found that one it does not control drivers side ac vent I also found the other one on the lower left of side of heater box it also does not control the ac vent please help
