Fuse numbers are in the owners manual.

Not much to go on here. Could be anything from a bad AC selector switch, pressure switch, compressor clutch/field coil or the system has no freon due to a leak..or something just unplugged. You need to give a few more details for diagnosis. What EXACTLY does it do? Does the compressor clutch cycle every couple seconds? Blowing warm air? Does the compressor engage at all?

There also a unit called a CCRM? or something like that. It is essentially a chassis relay panel and controls power to the compressor coil. Dont ask me where it is, I just know it exists.
