I have a question one of the Actuators in the back are clicking. Can that cause the front AC to stop working because of that? I have no clicking in the front.
I'm guessing the front one is messed up then. The front is blowing out hot air when it's on cold. The back gose to cold when it's on cold and hot when it's on hot. If the front actuator was broke would it make a clicking nose or it's just quietNo, the rear is independent of the front as far as temperature control goes. The clicking you hear is a broke temperature control actuator. Very common on the Gen2 Expy's. Tons of how-to videos on YouTube on changing them out. What temperature are you asking the front to put out?
Actuator circled in Red is the temperature control actuator .... Green is High / Low vent control ....
