Jammed Window

I just purchased my first Bronco. A 78 Ranger XLT(351, NP435) all the goodies plus some battle scars to boot. The rear window motor gos and gos like crazy but the window stays up, it could be the gear it could rust, it couldbe anything. I can't check it because the truck is locked up in my highschool for the weekend. Is it possible for the window motor of a 1980 beswapped in without any minor hacking. I found a running 1980 Bronco for $50 that I'm gonna dismantle for certain parts. Any info on 78-80 part swaps would be appreciated.

Sounds like your\'e into more than just the window motor swap!

They are completely differnt beasts! Personally, I'd take the 80, and make it into a nasty trail rig! Then you could restore the 78. Or depending on what goodies you got with the 78, fix up the 80 real quick and sell it for money to put into the 78... What engine does the 80 have? Does everything work? (4x4, tranny, electrical, etc...)Anyway, It sounds to me like if you take the tailgate apart on your 78 it'll probably be obvious what the problem is. Whichever you choose, enjoy your Bronco(s) and keep this board in your favorites folder. It's very usefull!

There's a nylon drive gear that goes bad. You can buy a new gearset at a good parts store for around $20 or you can get creative with some nylon stock from the hardware store and fix it for $1 or so. You'll need to pull the motor/drive unit to fix it. Easier if the tailgate is down. Try having someone run the window motor while you assist by pushing down on the glass.

Re: Jammed Window

All tailgates are the same on the big bronco's 1978 - 1996. I know this because my dad checked with a guy from ford and he cross checked the part #'s from the 79 (mine) with a 96 and guess what? they're the same. So there you have it, you can get any new part for a 78 tailgate. My dad ordered all the plastic and rubber pieces for the 79 (pricey $250) seals and stuff.
My 79 was having the same problem, and it was one of the plastic pieces (a round roller) that slides back and forth as the motor turns the two arms that move the window up and down. well it was off the track so it was real tough for the window to move at all (it had to be hand raised and lowered - taking two people) I think the new ones were 3.50 a piece and thier square with a bolt instead of circular and stamped on. We just ground the old ones off and the new ones work fine. I got a new tailgate from arp and just put some waterproof grease on all the moving parts in the window setup (after wirbrushing them. But check those slider brackets on the window and the slider piece, some grease and wd40 oughta get it going good for a while.
