ok so now its getting hot outside and starting to need the a/c, well no cold air is coming out, my heater is still working fine though, my a/c compressor is not coming on at all and i have checked all the fuses and plugsand they are good.....yall think the clutch went out? i am able to spin the front piece of the compressor, idno if that is supposed to be harder to turn or not...what can yall tell me?

i've had a similar issue with my 01 Denali. turned out the AC belt was ripped and gone somewhere on a highway haha. the ac compressor was hard to turn by hand but once i put the new belt on it spun perfectly fine. i assume your belt is still on the compressor since you tried spinning it correct ? if the belt is on, turn your AC then shine your light on the compressor and watch it for few secs. if it doesnt spin whatsoever then its a bad compressor. hope that helps

yea the belt is still on there, its just dead, it does nothing when i turn the a/c on

with the car running and ac on. i dont know if they are but if the clutches on these compressor are magnetic, very very carefully take a long prybar and touch the compressor clutch. it should be magnetized.

whats going to happen if i touch the clutch with the prybar???

 

[fatnlowtahoe504]

any other ideas???

 

[hassoun]

it will pull the prybar towards it since the prybar is metal

Keep in mind that most 00-06 NBS yukons, tahoes, and suburbans have the a/c compressor running all the time. Even with the a/c and defrost off. Its no wonder the compressors are failing early.
