Hi, my Mercedes 2000 S430 is acting weird. I only have 60,000 miles on. The power in the Driver door is gone and I can no longer control the Windows, Mirors, Seat position, Heated Seat... Plus The only window working in the entire vehicle is the front passenger window. The other windows were working at first but now stopped working. Also my stereo works but sometime when I start the car the sound is not coming out of the speakers and I have to stop and restart the car before i start hearing anything. All this didn't happen at once but little by little, one thing after the other. The fuses are good so I really don't know what is causing this.
Can somebody please give me advices? Did it already happen to somebody?

It sounds as though the drivers' door control module has quit. As for the audio issue, there are a number of things that can cause this, but you'll need an SDS to diagnose it accurately.
