- 300Sl, 1990, 103
Hello, I have a very nice 1990 R129 300SL. I just had it regassed yesterday, all went well, holds gas etc. Only problem is the compressor only works if you put a 12v feed onto the blue and green stripped wire on the compressor itself. The only other time the compressor will run is if you have left the car off for some time and you start it up, for about two seconds the clutch will engage and then trip out.
I think I'm being a bit hopeful, but does anyone have a wiring diagram for a 300SL, or maybe able to point me in the right direction?
Is there a relay for the air con? If so where is the blessed thing?
The receiver/dryer switch is closed indicating pressure (as far as I'm aware) in the system.
I have checked the compressor fuse, that's fine.
