2005 Deville AC problem.
 

Thanks for the help in advance.
The ac is blowing hot from the passenger side. I removed the blend door actuator. When I first turn the car on I can see the actuator working but after that I cannot het the temperature to change from hot to cold or vice versa. Is the problem still with the blend door actuator or is it the temp control on the dashboard ?

There are 2 actuators for blend door(s) there is one for driver and one for passenger side and rear seat. Drivers side is on top passenger is on bottom. Actuators are interchangeable.
