It's my first MB, so here goes... Odometer, trip odometer and tach don't work (speedometer does!). I need the mileage for work. It has turned some, one mile since I got it (.9 on trip), driven 200-300 easily. Also, passenger's window doesn't go up smooth. Goes down fine, goes up partly and sticks, sometimes moves on, usually doesn't Would get in and check these things, but can't figure how to get into them. Any help would be great.
