453 Window encountering resistance when rolling up

The usual problem is the gap within the weather strip is too narrow and the window backs down automatically, as it thinks a hand or head has got trapped in the glass. I had that problem when still under warranty. The dealership just enlarged the gap somehow in the strip, and there was no longer any friction.

But you seem to have the glass encountering the top of the window too tight, so I would say the whole door has moved in too far. Have a look at the door and see if it is in too far in. you can check to see if the metal tridion behind the door and the door panel itself are a smooth transition, and not a 1mm or 2 mm difference. If this is the case, the door will have to be moved out in your case, by the lock adjustment in the door being moved in slightly. Enough to free the window but still be rain proof.

I had the opposite movement of the door, ie, my passenger door was moving outwards over the years (screws in lock not tightened enough) and got to the door panel being 2mm proud of the side of the car, and was not a smooth transition between metal tridion and the door, and although the window operation was OK, the actual door locking was getting jambed up occasionally. So I had to adjust the lock in the door and move it outwards by adjusting the screws, this pulled the door back in. (the door catch latch itself on the metal tridion is non-adjustable, its the lock that is adjustable to move the door in or out). Good luck

Sitting in the parking lot waiting in my car and I had a few minutes to spare, so I pulled off the weather stripping to inspect and see if I could think up a solution. Didn't seem much, so I just put it back.

Watching the window go up and down, I noticed there was really a spot maybe half an inch across in particular that the window would seem to hit and couldn't overcome. I noticed that if I pushed that side in even slightly, the window would close without any problems.

This gave me the idea to try to clamp the weather stripping inwards and use a heatgun or blowdryer or something to try to permanently alter the shape of the weather stripping runoff channel ever so slightly backwards in just that area to hopefully clear the window. Didn't get the chance to try that, though.

When I got home, I went to close my window, and it just... worked? I tried to show my plan to my mom, and the window just closed on me. I tried it like 3 more times, and it just kept closing. So I guess it just fixed itself?

No idea how or why. I'll take it though!

Talking about side windows on the 453 coupe. Here in the UK we get black rubber lines forming on the windows due to bits of rubber seals residue coming off. If you do not clean these lines off every few months, then it gets sticky, and eventually it is difficult to lower the window. So have to remove these lines. Its to do with the specific seal the coupe has, as I also own a 453 cabrio and its a different rubber seal material, with no black line residue at all. weird! .....Not sure if you get the same black line problem in the USA.

Yep! Cleaned that off. Thanks for the reminder.
