My 1993 318i driver side window keeps poping off the guide... you know that little white thing with the clip that the metal rod with a ball at the end gos into... I took it apart and went and got a new on then it wasnt on the track very well so i rolled it up and the top of it crack so i just put it back in and when i roll the window up it was kinda hard to do and the back part of the window was kinda pushed foward... so i went to roll it up and it poped off again... these is a shitty peace that bmw made for a window....( oh yeah it not power windows)... so i quess i have to go get another one and try it again and make sure its perfect this time befor jumping the gun and rolling it up :mad:
