The AC recently went out in my 2004 G500. Local repair shop said that it needed a new AC compressor. One issue my car has had that I never really looked into is that the headlights do not go off when I turn the headlight knob to the off setting. They only go off when I take the keys out of the car. So I finally looked into this and learned it could be the SAM control module. I just brought the car in to do some other work and the guy mentioned something about the compressor not getting power from the control module. I found a video online on how to rebuild a control module. Looks like a pretty cheap and easy procedure and something that is worth trying. I am wondering if anyone can tell me if the control module does power the AC compressor.

In the pdf above, page 16-20 are the most pertinent.
Karl, Allen and a few others speak this language fluently.
