A/c problem 2001 w900

Last night before bedding down, all of a sudden, the fan stops blowing. I cut it off, wait about 20 seconds and hear the breaker reset. Cut fan back on...does it again. Did this about 4 times, then stopped. Fan was blowing but no cold air. Finally got stopped to check it out. found two bare wires. one runs to the compressor clutch. other runs to one of the pressure switches. Fixed those. Still no power at the clutch. Shorted low pressure switch, did not change. unplugged fan switch, it comes on. So fan switch is working. Any ideas? Could I have blown something? ie, pressure switch, clutch? TIA
