With the high low switch on the receiver dryer unplugged the compressor clutch does not activate. I have another problem however. I'm told I should not be getting any power through those lines as the Klima relay is supposed to detect that the low and high pressure relays are unplugged, and not send power for the clutch? Geez! And I thought maybe I'd gotten to the crux of the thing and just had to decide on new clutch assy or complete unit? Now I'm told there's a short somewhere causing these lines to power up.I'm not sure of the model of compressor. It's awfully tight under there with a lot of grease, oil and dirt. It's 1987 560SL. Did they use more than one kind of compressor?
I can't even find where the wire from the clutch terminal goes to put a multimeter in between to read amperage. I do love these old cars when they're working though. lol
