SAM control module

Post#1 » Fri Jan 11, 2019 3:36 am

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.

SDS would be my first thought, to find current and stored faults in your truck.

In the pdf above, page 16-20 are the most pertinent.

Karl, Allen and a few others speak this language fluently.
