Heres the problem I am having when I first got the truck it blew hot air so I added 3 cans of freon. After adding the freon the ac clutch would cycle on and off real fast on off on off on off. When I jump the cycling switch the clutch would stay on so I tried replacing the switch but nothing still the same problems. After a day or two the clutch would not even come on only when jumping the switch. Next I added some UV dye and found no leaks anywhere what the hell could be wrong? I have check fuses, the ground, for leaks and still no cold air.

You obviously have a leak somewhere. If you can jumper the low pressure switch and the AC will then engage the clutch it is low on freon. I had a very small leak at the AC pump where the two pieces mate together. You may want to dye the system again and check there real good.
That's what i had to do. So how did you finally find the leak, did you dye the system again?
Yep, swap out the compressor. Shouldn't be anything else needed unless you have other problems.

would giving the compressor a rebuild/overhaul be enough?
some say just take it to a welding shop and let them weld the places where its leaking.
is that ok??

Sure, that's a great idea. So, is the guy that recommended that gonna pay for the new compressor you'll have to put on when that doesn't work? (In other words, NO, that's a stupid idea.)
Just curious but what did a compressor run ya? Im thinking about gettin the AC in my beater going again. I need to get a couple cans of freon and try to recharge it first though. Im sure its going to be full of nightmares. It hasnt worked in 10 years.
