Re: 1999 300m radio problem

You could possibly have a short somewhere, Have you checked the door actuator, remove the door panel to check. You may also want to check your door switch while you have the panel removed. Also check the relay fuse under the hood, You can swap it with another just to diagnose if it is a relay. I've had most of the issues you've had, my analog clock also stopped, I had to replace it and now it works. I think they did a horrible job insulating the electrical systems on our M's. I've heard if there is corrosion on you battery or low voltage, it can cause some of these kinds of issues, though I have never tested it.
