Have you checked the fuses? Have you pulled the switch out to make sure that something is not melted or burnt up since it has been geeting hot, have you tested the main wires from the switch to where ever it leads to, I do not have a schematic but that would be some of the things I would look into. You may want to check and jump the low pressure switch on the drier to see if that kicks the compressor on. BTW I just got my air fixed and I am in GA so I feel your pain.

You can check the WOT relay. I have seen those go out suddenly.

It is on the passenger side in front of the strut tower.
