OK, I found a loose wire at the compressor, which I probably bumped loose when I installed the skid plate, though it took another month to stop working, and another month to figure out what happened. Added a little more r134 to top it up. Happy it wasn't the compressor, and that I have A/C during the Santa Ana wind season.
I'll try to swap out my alternator this weekend, in between tree trimming.

If it's leaking slowly there's a dye refrigerant you can add when charging it up, then you'll hopefully _see_ the dye wherever it's leaking / weeping and can -maybe- fix that .
I was told the other day that using later model W126 receiver/dryers and expansion valves changes them to O-Ring seals, usually much less leaky over time .
Rob, yes, there's a relay I forget where but just see if the compressor works, use your teat light to check if it has power to one of the two leads on it and ground the other, it will begin to run, be aware you'll grind it to dust in short order doing this is the coolant level is too low but it's a useful basic YES/NO test .
Keep us posted, O.K. ? .

Good luck on that one. I gave up on my 240's ac, after replacing most everything. When it worked it worked really good. My problem was a slow leak everytime. First time it lasted 2 years,then one year, then just part of the summer. I got tired of that and got a new car, ac works great. Max P.S still have my 2 -240's to sell. Its hard to sell cars from the side of a mountain 100 miles to the nearest big city(Spokane)

Hi,
My AC quite the other day, and I'm not sure if the compressor has gone,
or just isn't getting a signal from the controller.
Is there an easy way to test the compressor?
Every once and awhile, I've had the AC not work one day and be fine the
next, so I thought it might start working again, yet it hasn't.
I tried bypassing the low pressure switch to see if it had leaked, yet
the compressor didn't engage.
I heard the '85 has another control box under the hood too.
Thanks
