My 190E appears to have a frozen a/c compressor. There is a rubber bushing on the face of the clutch which appears to have torn all the way around. This tells me the clutch engaged and the compressor DID NOT MOVE. Assuming the compressor is frozen, is it rebuildable by a DIY'er? Anybody done this? I see rebuilt compressors for sale for $200 to $300 for my car but if the rebuild is substantially less expensive, I'd do it myself.

Thanks!
