Redo or undo?

How's your luck? There are remanufactured/rebuilt/repainted compressors on eBay for under $150. The $45 unit in my 87 300D is holding up well, BUT it doesn't have an rpm sensor. No biggie since I had already bypassed the flaky Klima relay. Which has me wondering whether your Klima relay is working. It should disable compressor engagement long before the innards are too difficult to turn by hand.
