    I have a 2006 1500 Sierra with the 5.3. A couple days ago I started getting a squeal, it is either the clutch or the compressor. From what I have read, even if it the clutch I might as well replace the compressor. I know I also would need to replace the orafice and drier. How much of a pain is it to change out? Can I unplug the compressor so I can use defrost and replace it in the spring?

    Anyone? I unplugged the wires at the drier this morning, heavy frost. Seemed to work fine for the little while until I got to work.

    if it makes noise with the a\c on it is the compressor,if it makes noise withe the a\c off it is the hub and pulley bearing,in any case it is cheaper to replace the compressor with an aftermarket gook unit. dont replace the acumulator unless compressor came apart internally.

    It seems to do it once the compressor kicks on. I haven't left it on long enough to tell for sure though. Am I going to be fine for the time being with it unplugged? I think it has a separate belt. Should I take that off instead?

    if the worst happened it would just smoke off the belt which only drives the a/c comp,the only danger is the remote possability that the broken a\c belt could knock off the other serp belt. take the belt off to be safe.

    I'd pull the ac belt. Could it be stretched? I'm not sure what year they changed, but there is no tentioner on the newer models, the belt is just stretched over the crank pulley. My 02 Yukon squeals on start up for just a second and then goes away, really doesn't bother me
