A few weeks ago, I was rolling the window down on the drivers side and suddenly something snapped and the window dropped down into the door. I took off the door panel and found that the two small plastic clips on the tracks had come off the window clamps. Upon further inspection, I saw that a piece had broken off on both clips.
I ordered a new pair of clamps and clips from eBay here: https://www.ebay.co.uk/itm/CLIPS-VW-LUPO-ELECTRIC-WINDOW-REGULATOR-REPAIR-FRONT-LEFT-NSF-PAIR-OF-2/361102620447?pageci=a58f9161-d984-43e6-ba41-94e2079067f7
The problem is that they fit very tightly on the tracks, but they slide easily off the clamps, which means that if the windows are rolled down and I shut the door, the clips come off the clamps. I tried using a pair of pliers to tighten the clamps onto the clips, but that didn't work. I'm not sure how the clips are meant to be secured onto the clamps.
Any advice would be appreciated.
