I'm having trouble getting my passenger side window to work properly. I've replaced the window rail already as the previous one was rusty and bent. But even when the rail is right at the bottom, the window is really stiff to go down, you really have to force it down and then back up again. This has caused to light scratches in the glass.
I think when the car was resprayed it had all new seals, could it be the seals are just to tight and are gripping the window in place?
It could be the seals, but it could also be that the mechanism needs a bit of adjusting after you replaced the rail. As few of the allen headed bolts allow for adjustment...
Will take a look after at adjusting those after, but even when the rail isn't attached to the window, it's still very hard to get down. You have to put your hands on the glass and really force it down? When you try to bring it down with the mechanism, the glass stays up, but the mechanism moves down
It is usually the U- shaped felt that goes around the channel inside the window frame.
When it gets old it swells up, so making it difficult for the glass to go up and down.
