MY CAR MERCEDES WONT START
I have a 2009 Mercedes c300 and last night the engine went on, my turn signals, windshields, Ac wouldn't work. This morning I couldn't event unlock with my key. What could it be?
Could be a dead or discharged battery.
It sounds like an electrical problem and one that may require you take it in for service given the number of electrical issues you're describing.
THANK YOU SO MUCH!
I have a 2009 MB 300 C. Repeatedly, my car would be dead.. dash board blank, key would not open door, no charge at all. We thought it was battery, then told it was the alternator which we had replaced. However; it was neither. It was the "headlight switch" that was draining the battery. Even though the lights appeared to be off, they technically were not. Once we left the light switch set at 0 not Auto, and only allowed them to come on automatically when dark, the problem stopped. This is a temp fix until I get the headlight switch replaced.
