My rear air fan will not come on by using either of the controllers. The main air works but not the rear. The fan will not turn on. I checked the fuse and it is fine. Do you have any ideas?

You will have to check and see if the switch is working. YOu can do this with a test light, by probing the line going to the switch and then the different colored wires going to the blower. If you have power to the blower, then it's the blowr or a ground wire that isn't grounding the blower.
