After taking a nap in the parking lot at my job, the driver's seat (power seating) -- the passenger seat did work-- I had laid back could not be readjusted. After work I went home (3am closing shift). Two days later no power whatsoever. I jumped the battery still no lights (electrical lights and headlights). Even when i turn the key over there is no sound or click. When I needed a new battery few months back, there was a distinct clicking sound. The battery is definitely good (new).
No previous electrical or wiring problems
But I still can't get the engine to turn over or the lights (oil, engine, ABS, etc) to come on when the key is turned to the second and third position.
Any ideas it is a Mercedes ML430 - 1999.
