AC help

1997 F150. The air conditioner doesn't work on my son's truck. It hasn't worked all year. When you turn the AC on the compressor doesn't come on at all (does not engage and turn, not even a click). We checked all the fuses and can't find any that are blown. If the freon is low or out will it keep the compressor from coming on at all? Where to start?
Thanks, Joe

Yes, there is a low pressure cut off switch. This link will take you to another thread with a electrical schematic/block diagram of the AC system. Good luck!

See the schematic in current thread started by mechman787.

For more information, see the FAQs in the HVAC forum.

Between the two, all your questions should be covered.
