So Monday I had to have the A/C compressor replaced on my 11' Prostar due to the clutch deciding it didn't want to go to Little Rock with me lol.
By no means am I blaming the shop that did the work, I think they did an excellent job with a very reasonable price and hospitality. Exit 37 truck repair in Arkansas preformed the work. I list this information because going back to them is not an option for me unfortunately.
For some crazy reason the belt appears to slip around the groved hub, and clutch won't spin. I can shut the truck off and hand turn the clutch. Fire the truck back up and same issue. Shut the truck off and give the main pulley of the compressor a few, very gentle and I'm serious about gentle "tings" on the pulley, I can start the truck back up and the compressor will run for an undetermined time just to stop again at random and repeat the situation. I've thought maybe a bad tensioner but I don't not get any belt smoke or squeal, chirp, or wobble in the belt. Belt is nice and tight and not terribly old either. No other pulley has this issue either. It's like the compressor is too slick?

The inside part of a/c pulley has a bearing inside of it and will spin free when a/c is off, pull the belt off and ck if the part that belt goes on will turn free?If it does go get a socket or wrench and turn a/c comp. to see if it turns with/out lock/up at places, trash in lines may have got in new comp. and made it burn up?

Yeah, it does just sound like the compressor clutch is engaging and disengaging as it's supposed to. When the ac is switched on, it will run until the body controller senses refrigerant temps are cold enough to shut it down. There is also pressure sensors for it too. So the ac compressor doesn't normally run 100% solid all the time. Is the ac not cooling?

That is possible. Without tapping it, try to wiggle the wiring and connector to see if you can find a bad spot.
