Touchy today? :) The clutch and stuff can be replaced but you have to evac and refill the AC to do it so that's a hundo right there easy. Which AC system is that using because if it's the old stuff they won't touch it you'll have to convert it over. I understand what there saying about where the noise is it really is a tricky thing bro knowing for sure man. The fact that it goes away worries me that it isn't the compressor bro.
