I tried to find a thread that mentions this, but I couldn't seem to find it. My 1996 Bronco's driver's side window sometimes goes up unevenly and then jams. I was wondering if this is the regulator or the channel rubber. Any assistance on this would be awesome.

 

Yes. Either one or both. Is the window weatherstripping in bad shape? Remove the door panel and look at what is happening as the window goes up and down.

 

What did you find out?

 

The rear channel is adjustable so the window cannot go sideways too much
Tighten up the channel and lube the track felts with Ford mini vent lube
This is the stuff
