I have a question about my 1985 300D. My a/c compressor is cutting out at idle and at low cruising speeds. If I put the car in neutral and rev the engine up to at least 2500 rpm, it turns back on. The tach is not affected when this happens. I was thinking it could be the Kilma relay (since this a/c compressor doesn't have a speed sensor I am not sure what the Kilma relay's purpose is. The wiring diagram on my cd rom manual looks like a bad photocopy and is useless), the ovp relay or something in the acc itself??. When it is working, it is like a meat locker inside the car. Just thought I would bring this up to see if anyone has had similar experiences on this year/model 300D.
