In dash ac

I have a 2003 Coachmen Mirada class a motorhome. At this writing I have a electrical problem with the in dash ac. The compressor and clutch are working but I have no power from the power distribution box to the clutch. I believe I have a bad fuse or relay for the AC but the power distribution box does not identify what each fuse or relay powers. The inside of the power distribution refers you to the owners manual which also does not give you any information to identify which fuse and relays control the power to the AC. Can anyone give me any information about the fuses or relays that power the AC or a contact that can provide this information.

Are you sure you have refrigerant? I've had systems stop running the compressor when the pressure in the system gets too low so it doesn't damage the compressor. Or the pressure sensor itself could be bad. Just a thought.
