Window closing issues

[powrguy]

I have a 1998 T4R. Recently, the power window on the drivers door started slowing, and reached the point where it needed help, and up-and-down bursts, to get it closed fully. I figured the regulator was allowing the window regulator was worn out or bent, as the tailend of the window seemed to rise while the front dragged slightly lower.

Bottom-line; I bought a new regulator and motor, and installed them tonight. What I noticed when I removed the old one, and the glass, is that the rubber that lined the front window channel seemed closed together, which I thought COULD cause binding. It's original rubber on there, too, although it LOOKS in good shape. I removed the front track to see if it was bent or deformed, and it was fine. HOWEVER, when I re-installed the rubber, it still seemed to be squeezed together, with only about 1/16" between the lips that ride the glass.

Also, as the glass comes up, it pushes the top of the rubber overlap on the windshield pillar away from the pillar, and further interferes with the window closing.

Anyway, with the new regulator/window motor installed, I put it all back together and STILL have the same issue as before (won't close normally/needs help/needs short up-and-down bursts). I tried liberally spraying silicone spray in the rubber channel, which didn't seem to solve the issue, either.


What is the rubber called, and has anyone had a similar issue? We had some sub-zero weather and it started about the same time.

:ybrick:

Well in the Autobody world we called that rubber the window channel weatherstrip. But who knows what Toyota calls it. I've face similar issues, but not on my 3rd gen. If you run the window without the w-strip, it will work fine I'd bet, but don't blame the rubber just yet. In other vehicles I've had success shimming the bottom, or upper mounting bolts of the regulator to acheive better alignment to the channel in the upper movement. I'm not sure if that's even viable here, but worth a look. Sadly the other potentiality is the motor itself. Cold weather will often highlight a tired motor. My 89 Landcruiser has tired motors on 3 of the 4 windows. So bad I've had to walk around to each window and help it up on cold mornings. And a cold morning here isn't even as low your high for the day. Well, please let us know if you solve it!

Well, since the problem was the same before and after replacement of the original window motor and regulator, I suspect it's something else, such as the weatherstrip or the channels. I looked the channels over and even removed the front one (which is the one most-binding), and they both do not look damaged.


thanks

Did you lube the window channels?
Try this if you haven't. https://www.youtube.com/watch?v=Ax60oNhnh0A

edit: I see now that you already did, sorry
