Hi there! I have a 2003 ML500 W163 that will not start. Half of the instrument panel lights do not work and engine will not crank over. The only panel lights that are working is the SRS/Airbag and the High Beams. I can view the time and mileage. I've check every fuse, all ok. Battery did die; we replaced with new Battery and its working; fully charged. Many other things in car working, but many others not. Seat warmers do not come on. brake lights will not come on; license plate light not on. Gear shift isn't locked and can move. Getting ready to check relays for start and instrument panel and the ignition switch. What else could I look for that would possibly be wrong. This all began when battery began failing.
