With the heat coming on I decided to browse through eBay for A/C compressors, rebuilt or what have you, and found that a new compressor is about the same price as a reman, at least from buyautoparts.com. This is partly due to where I bought it (everyone else seems to want more) but also because it's a common GM axial compressor which is used on many vehicles. It's a really small little sucker that can turn 7,000 RPM, and Mercedes wisely used a V-belt pulley which makes it easy to source.
Last June 5th we broke down and bought an air conditioner. We went to Sears to buy it, because they had 'em and nobody else in town has much selection. This turned out to be a gigantic mistake. We used it throughout the summer, and then put it away in the back room. When I brought it back out the GFCI-equipped power cord's breaker decided to blow every time the unit was plugged in. I figured it was just the cord. The girl I talked to on the phone said that servicemen carry that kind of part with them, which turned out to be a lie, shock amazement.
