    Rear window/gate ???\'s

    I'm looking for some info on my rear power window/tailgate. I attempted to get inside the gate to fix the slow/stuck window, and before I knew it the rail that holds the window got bent and now the whole thing is held up by rubber wedges. I have no idea what else is broken in there, I can't even look at it without getting upset. The rear gate is in rough condition, and I'm thinking of hitting some junkyards to find the whole assembly-power or manual. Anyone know what other years are compatible with an 88 full size Jimmy, f'rinstance, can I swap it with an '85? Also, any resources for aftermarket power window assemblies,(less expensive than dealer)? Any resources for rebuilding the guts correctly-helpful hints or secret assembly tips? Thanks!

    all i will say is good luck with finding one in a junkyard. it took me forever to find one.

    BTW, does anyone know how to put down the window on a power tailgate if you dont have the key? I need to do this to get my new gate in 2 days, but i dont know how.

    Not sure on Killdozer's problem... but to roll the window down.. you have to remove the tailgate access panel, and there is a screw in there.. think it's in the center that you can crank down with a drill just find the correct size bit and crank her down..

    Shaggy, on the power gates the regulator is driven by a cable from the power motor, like a oversized speedo cable. Just undo the cable from the motor end and chuck the end of the cable into a drill and slowly reverse the drill and the window will go down.

    That cable is also the source of most "slow" window problems. The factory grease dries out with time and binds the cable inside the sleeve. It gets worse in cold weather. The cable doesn't come apart so you can clean and regrease it, but they aren't too expensive from the dealer. The window should work fine once you replace the cable.

    I recently replaced the side tracks, the rollers, and window sash on my '90 Jimmy. Your '88 should be identical. Go to your local Chevy dealer and have him print out an exploded pic of the rear tailgate. This will give you a good idea as to what you will need and how it comes apart. Based upon what I saw in my tail-gate, I would not go to a junk yard for parts. Most of the problems are caused by dirt and rust. The dealer may be a little higher, but I can't imagine oredering the parts by mail and having problems with returns and wrong parts. I had that problem with some of my parts. If you broke the window sash, it holds the glass in place by means of a thin rubber strip. The only way you can purchase this from the dealer is in a 100' roll. I found that the felt in the window tracks on the sides had all worn off and was layin in the bottom of the tailgate and stopped up the drain holes. Installation is easy, it just takes a little patience.

    While we are on the subject. What's involved in converting a crank window to a power window? Is it worth it?

    Thanks Derf...Thanks everybody else, too. So far I've received more help in one day from this group than after a whole week of scrounging junkyards and dealerships. Well, at least the glass is covered by insurance.
