Send reply to: fj55@tlca.org Date sent: Wed, 14 Aug 2002 23:00:52 -0700 Hello everyone, I am in a jam and don't know how to get out of it. About a week ago I lowered my rear window and was unable to raise it. Yesterday I was able to take some time to try and fix it, when I discovered that I can't get at the window mechanism or switch because the lowered window is in the way. Does anyone know what might have caused this? and how I might proceed? The dash switch doesn't seem to work (i.e. no noise at all to indicate power being sent to the rear window) and the key switch on the rear door only provides power to the "open" direction which of course goes nowhere as the window is already open. Before I start tearing into it (i.e. remove the rear window from it's track and pull it out to access the wires and motor), does someone have a clue what has happened and how best for me to proceed?

There is a switch that is located where the tailgate closes against the body, on the driver's side. The window motor can only operate when this switch's button is depressed. This is normally activated by a plastic doohicky that is vaguely wedge shaped located on the tailgate. If it is broken (often the case) or the hinges are really messed up so that the button on the switch isn't fully depressed, you can't operate the window. At least with the glass stuck down, you should be able to lower the tailgate. Then try using a clamp to hold the switch button down. You should then be able to operate the window, and figure out what's actually wrong. Good luck, Bob Schenker From: "Gary Schmauch" To: Subject: Fw: [FJ55] help with stuck rear window...

Toyota calls it gear worm tailgate lists at $26.32, includes pinion gear and shaft, plastic driven gear, and new retaining clip. Same as I used to buy from Offroad West when I could still contact them. Do yourself a favor and clamp the arms in place for when you disassemble the gearbox it's a pain in the butt to re-"time" the quadrant gears if you disrupt their mesh. Gary S
