Hello, Im a newbie here.
My 99 ML320 was poorly maintained, Ive had it a year and unfortunately the engine needed to be replaced....several thousand dollars and a big PITB later, My car is running again.
However, the wind shield wipers wont stop running, the gas gauge is not functioning, the lights flash every 10 minutes, the external temp is broken.
That mechanic is not touching my car again, guess I have to see the dealer. Sounds like a computer issue correct? any ideas?

To top of the fiasco, the window button disengaged and the shotgun passenger window is stuck entirely down.
