posting for a friend
I have an 03 that when I'm on a hard pull the compressor cuts out like it should I guess but then it won't re-engae after the hard pull is over, I have to bring the truck to a stop, kill the engine and fire it back up for the a/c to start working again. Is there a time delay built into the circuit to prevent high pressure starts? any thoughts? thanks!

is there a cut out programmed in the computer that cut the compressor out when there is a call for more power, it seems like when I'm pulling my 24 ft trailer and have the tow/ haul switch engaged the compressor wants to drop out on a pull and then never re-engages till I shut the truck off and then it returns to normal. or isit something else?

Have you checked the clutch gap?

its normal to cut at on high loads.. it should come back on after a few seconds.. i believe...not more than 2 mins max

If this happens more when the engine is hot, check the clutch gap, should be around .02, or a business card will fit "snugly" in the gap, if it's more, then remove a shim.. You can test this by when it stops engaging, tap the outer hub inwards (Carefully) and if it starts, it's the clutch gap.. Hope this helps..
