How many climate control actuators are in a 2008 Mercury Sable?

Hello, you have a temperature blend door actuator for the driver's side and the passenger side. This is with a dual zone climate control set up. You need to figure out which side is not responsive to hot and cold controls -- the one that doesn't respond is likely the one that needs attention. Now, it's important to note that the motor may not be the problem. There could be a wiring concern or a concern with the plastic door of the plenum itself that turns from hot to cold.
