A word to the wise...DO NOT SLAM YOUR DOOR SHUT WITH THE WINDOW ALL THE WAY DOWN AND WEATHER STRIP NOT IN PLACE!
As for me, I guess it's off to BMW to have them fix it. Oh well. |
It's an $11 part. part# 51328146243(left) part# 51328146244(right). Comes out really easy, one bolt through the door jamb and a slot up top. Or you can take your old one and have it re-spot welded or riveted. It wouldn't hurt to have the weather strip at least partially in place, but the slam test is absolutely necessary. It's the most important part of the procedure and subsequently the most often overlooked step. But you're right, it only takes a second to position the weather strip or stuff a rag between the window and opening to provide some cushion. I highly doubt a couple millimeters of travel caused your welds to fail. I mean the physical action of the window coming off track puts more stress on those welds than slamming the door does. It's probably a good thing that it happened now as it most certainly would've eventually happened later. Best of luck, hope you get things sorted out.
