Heya...<p>does your guys' A/C compressor come on with a bit of a clunk, and then hisses a while? Sometimes the hissing also happens as I accelerate from a stop, without the clunk. I had Volvo take a look and they said those noises are within spec. The A/C is ice cold, the fan and all the flaps seem to work, but still, I don't trust it somehow. Am worried that some belt or pulley or clutch or whatever there is between A/C and engine is going to crap out soon. Any hints?? <p>Thanks!
