Window roller jumped out of the channel why?

[Dr Gil]

What would cause this green roller to jump out of the window roller channel? The symptom of this was that the window wouldn’t roll all the way up. Once I got into the door, I was able to put this roller back into the channel and the window work rolled all the way up.

I’m sure this will happen again if I don’t fix something. What is that something that caused this roller to jump out of the channel?

Quick WAG. Channel holding glass has slid on glass causing roller to extend beyond channel end. Fix: reposition glass in channel to position correctly so roller does not roll out at full extension.

Is the grease supple ( not tacky / dirty ) in all grease zones, also clean the vertical tracks out. If that’s all good the regulator is possibly bent. Usually when I see that in any other cars shizz is all gummed up. Your stuff looks purdy clean but looks in photos on a tiny phone screen can be deciving.

Already mentioned, something is bent, loose, broken, etc as the the green roller wheel should not come out of the track if everything is correct. Whatever the cause (glass/regulator loose/bent) it should become apparent once you get the door panel off, open the vapor barrier, and watch the regulator and glass move while pressing the up-down switch.

Pull the glass up and ensure there is some sticky tape in the channel. The sticky stuff should keep the glass seated in the channel preventing it from bouncing.
I use used double sided sticky tape.

The common cause is the rubber "filler channel" that sits on the bottom of the glass and fits into the guide channel.
After 29 years, that rubber, and all the rest of the rubber bits on your truck, don't owe you anything more.
What happened is the guide channel now slips on the rubber (or what's left of it) and will likely continue to do so.

Filler channel rubber is still available and inexpensive. I replaced all 4 along with all the window guide rubber when I got my 97.

I had this happen on mine. The glass can rotate enough in the tracks and the slide can shift to the right enough for it to come off track.

I ended up using toyota fipg to re-adhere the slide to the glass and greased the track the wheel rides in and solved the issue.

Also check these two bolts on the inner door skin.

If these are loose, or shifted, the regulator can twist/tilt inside the door. The window glass will tilt, the glass won't follow the rear edge of the door frame, and the front roller can come out of the guide channel

I did all that you mentioned above. I don't see anything obvious of why that roller would come out of the channel other than the channel needs to be moved ro the right as mentioned above. Thanks for your response.

That's something that hasn't been mentioned yet. I will check that out. Thank you.

As mentioned, the glass can come up out of the "window channel" that attaches it to the regulator or the window channel
can be loose where it attaches to the regulator:

Thread 'Rear window falling off track'

Dec 14, 2010

My son opened the rear passenger window the other day and it got stuck about half way down. I took over the controls to try and see if I could finagle it either up or down to get it to work. I was able to get it to come down a bit more then it fell. When we got home, I took the door apart and was able to get the roller back in the track and the window up. But I noticed that when I cycle the window, as the arm comes down it nearly comes right out of the end of the track and as it swings back, it gets stuck. The track is attached to the window with a metal piece over a rubber gasket...

Post in thread 'Window Glass Woes'

The glass pulling out could mean the metal channel is rusted and has lost it's grip on the window.

The window channel uses a pinch hold to keep the glass in place along with a rubber filler piece. My DS window channel had rusted badly so went ahead and replaced it while I had the door apart and before the window came loose. The window below was replaced sometime before I bought the truck but the widened channel trapped water which led to the rusting. I had talked to a couple of window glass techs who said they just use a urethane adhesive instead of the filler but I went with the FSM...

The beauty of ih8mud is being able to see others having similar challenge with windows.
Have had similar prbolem for years with Left passenger window. The glass would come off the track the oddest times. Got so good at taking off the panel and reaching with factory tool bag.
After reading about slow regulators, glass coming off, cold roll up etc. It gets expensive quickly throwing parts around.
Another post of "How did our 1997 FZJ80 run, brand new?" Including windows?

Having done to much to our 1997, it seems many repairs are associated with being dirty.
Have come to realize, that after this many years and miles, the dirt chlormag build up is everywhere.
The rear sliding windows are classic repair. Took apart to be amazed at the build up and deuteration of window frame.

Windows
Took apart the glass, track, and rubber door channel. Accessed the motor and track mounts to DBL check bolts.
Yes bolt two towards front little loose.
Removed lower rubber for glass to sit on track. Clean gasket all sides including track
This gasket has to slide onto track from either end, with glass pushed onto track.
Fitting the glass onto track, with track as far back as possible has helped.

All of the rubber molding have a small but significant build up of grime.
Clean window moldings by pulling out a side, one at a time and cleaning.
No complete removal. Also allowed the rubber gasket to stretch back out to fill corners.

Cleaning all sides and track get the system back to Original specs. Was surprised after cleaning all the channels and rubber moldings the smoothness of window.
Go to cleaner for everything is GOOP, rinse with weak dawn soap and wipe with rags.

YKNOT123 has time to clean
