Just to jump in, when I was at Volvo the compressor clutch would wear out. Using a feeler gauge measure the clearance. It should be between 0.3 and 0.5 millimeters. If you are out of spec here is the repair procedure for the clutch. Here are the instructions in the diagrams below on how to replace the ac compressor clutch coil. Check out the diagrams (below). Please let us know what happens.
