While I'm fixing all the issues on this GP, I am revisiting this old one. Since I've had the car, the passenger side door does not stay open. There is no resistance in the passenger door hinge at the med and wide open positions, so the door will swing shut. I noticed today that the spring on the passenger side is on the BOTTOM, but the spring on the drivers side is on the TOP. This doesn't look right. The spring is never in contact with the hinge mechanism so it offers no resistance. I took a few pictures.
I think what happened was the car was in an accident before I owned it, and the body shop installed the hinges incorrectly. Can someone take a picture of your passenger door hinges and post for comparison?
