John, is the regulator adjusted correctly or is it maxed out when you get it as high as it goes?
If the regulator is bad, which I doubt, I do know of a NOS one here at one of the parts houses!

window
John- Check to see if your lift mechanism is bound and will not let the motor/gearbox drive it far enough to lift the window all the way up. The motor will turn the gearbox until something stops it- like the window going all the way up or being all the way down. No limit switches in there to electrically de-energize the motor- that's one reason the plastic gears split. I would check to see that the mechanism itself is not binding somewhere somehow that it won't lift the window all the way.
One note- if the two quadrant gears become unmeshed (dangerous situation really as the spring that helps lift the window is a strong SOB) you must be certain that they are re-meshed in the proper position with one another. I've been down this road before.
Good luck I am interested to hear what you finally determine to be the culprit. Gary S (Shmukster)

I think Gary nailed it with the gears not being meshed properly. I, too, have been down that trail, and it's a pita.
That be the ones!!
and if you didn't have any resistance when the regulator was out, me thinks your spring is shot, which could also add to your problem

John, it's the relationship of the arms to each other. The number of teeth enagaging each other and where....
Now, you got 2 arms, each with the semicircular gears. And one engages the drive gear from the motor. And the other arm turns off of it...
You know that.
I believe you have to pull the motor slightly, to disengage it from big arm, then you can rotate the arms to disengage them from each other. Then you have to figure out where to re-engage the two gears to make them raise perpendicularly simultaneously. And this may take several tries. Watch your fingers. Most easily done with the tailgate folded down. Defeat the tailgate safety switch so you can raise & lower the window (Horizontally now) while watching from above. You should see what I mean.

Pighead, what I am confused with is that I was able to swing the arms together through their full range of motion before I put the regulator in the tailgate. So I'm confused how it could decide to bind up when it was smooth before
The issue is that the arms need to be in the correct relationship with each other. You may be one tooth off in meshing the arms. You need to "unmesh" them and skip a tooth one way or the other before "remeshing" the arms.
John the issue, as I understand it, is that if the two arms are not correctly sycronized then the window doesn't roll up straight but off to one side or the other. The arms can still move smoothly though. The regulator also needs to be adjusted in the tailgate, there is room for movement there as well.
Isn't that just like you, John...always choosing the hard way just to prove us wrong.
Well, I do have a spare motor/regulator (unsure what year), and a tailgate or two as well...How about you show us a pic of what you got?

Hope these help
Did you adjust the arms/channel horizontally with regulator assy out of the vehicle? that could be your issue. although it looks like you'd rest the back plate flat and adjust the arms equal, it's not like that. if you stand the motor upright, one arm is almost straight up and the other is angled.
i learned that one the hard way. fortunately, i had an extra motor to match everything to.
