Driver rear window wont roll up

[Sigpros]

Hi everyone,

Been lurking the site for awhile reading up on my trac. It has been a great truck so far except for the moon roof exploding and now the driver rear window won't roll up. It goes down fine but wont come up. I switched the switch from the passenger rear and nothing. it wont work with the driver control or the rear control. I took the regulator out and grabbed a used one at the local junk yard. Put it in thing went down slick as could be. But it won't roll up either. Any ideas? Thanks for any help guys worse case I get it up and leave it unplugged so it stays up

Thanks. It's not the back window its the drivers rear widow. not sure if I am explaining it right

You could try swapping motors. The motor has less strain to lower the window then it does to raise it might be a weak motor

Well it wont go up at all just plugged into the power supply. So I pulled the panel off the other rear door and plugged it in. Goes up just fine. So I guess I have a wire problem. Now I just need to figure out how to track that down

Could still be motor

You guys aren't understanding. I plugged it in on the side it goes not installed in the door. Nothing. Walk around to passenger side plug it in not installed in anything and it works fine. So if its the motor why will it work on the passenger side and not the driver? Either of he regulators?

i mentioned maybe a weak motor but if "bench testing" it off the regulator and drivers side plug is dead and the passenger side is good i would agree that your issue is the wiring. a good man to get in touch with is NCranchero he has just about any wiring diagram you can think of

seems like wiring

I had the same problem recently [window down only and would't go up] and also thought it was motor, then regulator, then switch. turned out to be a broken wire in the driver door jamb boot that i only found due to posts by Koda2000. here is a copy of his posts on the issue [sorry, I am new member and don't know how to provide a link to the thread involving this issue]:

"regarding locks and windows: the wires tend to eventually break in the driver's door jam area because of the door being opened and closed a ga-zillion times. there is also a wire connector under the rear carpet which gets corroded and/or comes apart. both of these problems are very common on older gen II's.."

"you take the rubber boot back covering the wires and you take the cover off the black cylinder-looking thing in the door jam. pop the little black cover off the center and there's a 10mm? bolt under it. it's tight trying to work in there, so taking the door hinges loose is an option."

"all the wires for the locks and windows pass through that cylinder. you're looking for any broken wires."

"and here's a lnk to a youtube video regarding the corroded splice in the rear that causes problems: http://www.youtube.com/watch?v=N88FYRW0B1w"

good luck. At first after opening the boot i did not see the broken wire, but pulled the boot back/down and then saw it.

Thanks guys! Will check that out tonight.

It was a broken wire in the boot. Yellow with a blue stripe if anyone is wondering which wire runs the drivers rear window up. No way to splice it in such a tight spot so I removed the kick panel and pulled the wire out. Added about 4" of wire and fished back through. Hooked it up and now it is working like a champ. Sprayed some white grease on the track since I had it apart and put everything back together. Thanks again for the help.

thank Koda2000 - he's a wealth of knowledge.
