I have a 2005 Monte Carlo SS with dual HVAC control. The passenger side control works fine, but the drivers side blows cold air.I have a hunch that it may be the actuator motor. If this is the case, how can it be checked and how hard is it to be replaced. Could there be any other possible problems?

 

The ac system is low on refrigerant.

 

i have a 2000 ls and that is what is wrong with mine it blows cold on one side and hot on the other, that door is not opening and closing all the way.it is not very hard to get to just be careful not to break the nipple end of you blend door where the actuator connects

 

Can anyone tell me how to get to the damper door on the drivers side. My wife is not happy with cold feet!!!

 

Does anyone have instructions on changing the actuator? Location, etc.

Thanks
