Klima relay.............it might be desoldered. You also might check the wiring to the clutch, sometimes the wires more or less rot off. Outside shot, compressor RPM sensor stuck in the rear of the compressor. Fuse boxes will corrode and "carbon arc" the fuse, killing power but not having a blown fuse.


Next time it fails, see if you have power to the low pressure switch on the dryer. (same power source)

Check the tension scale on your belt tensioner. There is a speed sensor on the a/c compressor that kicks it off if it senses belt slippage.

Good luck,
