e46 Coupe window not closing properly
Recently my driver's side window (frameless on the coupe) will often not close properly. It goes high enough, but at the wrong angle, leaving a small gap, with the top of the window hitting the trim strip instead of tucking in behind it tightly to the seal.
It's ok if I shut the door and push the window in at the same time, it's often ok when driving at low speed, but will almost never close properly at higher speeds, due to wind I guess.
There appears to be a little play at the top when rocking the window in and out. Obviously this wouldn't happen if the window had a frame / guide, as in the saloon / sedan.
Anyone have experience of this problem, or can offer any advice on what part may need tightening or replacing to cure it, before I take the door panel off and look around ?
