AC compressor will not come on.

AC compressor will not come on.
I've read a lot about this issue, but can't figure it out.
2003 F150 SuperCrew 5.4L, 4X2
Air Conditioning worked perfectly last night. Nice and cold.
This morning, no worky. AC compressor clutch is not engaging.
Here is what I've done, engine running, Max AC, clutch will not engage compressor:
Any ideas?
Thanks,
Jimmy

Here is what I've done, engine running, Max AC, clutch will not engage compressor:
- Jumpered low pressure line switch
- Jumpered high pressure line switch
- Wiggled switch on compressor (could not get it to release, because I couldn't figure it out)
- Clutch will turn by hand, engine running and not
- Attempted to service low pressure port, but since the compressor was not running, the pressure at this port was 80+ PSI.
- Checked AC clutch relay, AC Fuse, and AC diode
Any ideas?
Thanks,
Jimmy

Did you check the FAQ already...
I think this is likely your AC clutch gap, given what you described. Did you try tapping the clutch plate with the handle of screwdriver, to see if it engages then?

Welcome to FTE, Nigel!
He was referring to the clutch gap. You adjust the gap by removing the center bolt in the clutch plate.
Checking and setting the clutch gap is outlined in the sticky at the top of the Forum.
Also, it's preferable to start a new thread about your issue instead of resurrecting an old thread. Just FYI.
