1) The A/C fuses are: 12, 17, 20, 21, and 24. All of these are in the fuse
box under the driver's kick panel.
2) There IS a clutch relay. If it fails, the clutch will not receive power.

Since most electrical problems in older cars result from bad wiring, bad
grounds, and bad relays, start here:

There are grounds all over the place, and they are common to many
components. If you are not experiencing problems with other electrical
accessories, your grounds are fine.

Also, have you checked your sight glass to make sure you've got sufficient
refrigerant? The sight glass is immediately outboard of the compressor.

Good luck.
