Right it keeps for some reason falling to one side. The B pillar side of the window seems to be forced forward when the window is asked to go up and then jams slightly if you don't pull it tight against the B pillar part of the window(ie towards the back non slanted side of the window).
I have taken the door card off and wasted Dynamat now to try and fix. Have had the window out with the reg too. And there doesn't seem to be anything missplaced.
Anyone know how to fix this or has had something similar??
if the silicone does not work (9/10 it will), look at the channel roughly where the window starts to tilt, it may be that the rubber channel has a 'pinch point' and this causes the window to tilt. Solution is easy, get a pair of cirlip pliers (or ones that open outwards as you squeeze) and use them to spread the channels back an equal distance apart again. That will defo sort it.
well, mine got stuck on the A pillar, just by the door mirror, my window was tilting down at the front. If it gets stuck at the same point there is probabaly some imperfection in the rubber channel, small ones are fixed by the spray, larger ones by spreading the channel apart again.
