2001 A/C clutch not working, no power
#1

Here is the wiring diagram
In 2001 the AC is controlled by the computer
When you select AC the computer(PCM) gets that "demand signal"
It will then connect the GROUND, from the two pressure switches, to the GROUND for the AC Relay.
AC relay has 12v with key on but no GROUND so stays OPEN
When grounded, AC Relay will close and send 12v to AC Clutch on compressor
That 12v for the compressor comes from engine bay fuse box Fuse #F1.25, 10 amp fuse <<< check this first
