AC out

[JSchuricht]

I am currently several hundred miles from a good parts store and my AC has decided to go out. It only seems to happen after the truck has warmed up. I can see the clutch shut off from my AE and it will occasionally cycle back on momentarily.

Is there anything common that could cause this? I don't have access to a pressure gauge and suspect that I may be low on refrigerant. I am hoping to get something working before driving 650mi on a 18' wide two lane road with a 8.5' wide trailer tomorrow. Any ideas?

while truck is running and ac on try softly tapping clutch plate. if it engages and stays you need to shim or replace either is a piece of cake. but also could be low on refrigerant

x2 on what rick said.. I had to take a little shim out of mine and its been working fine for the past year and a half

I measured the gap and decided to remove the shim, but the compressor was still turning off. Started playing with the switches and found a loose connection in one. Hopefully it stays working. Thanks for the suggestions.
