it's my third tracker, non of them had properly working drivers windows.  Rolls down easy but jamms going up, have to push it towards the rear to get it up the last 2 inches.   Anyone have a fix for it? 

Incidentally, so is the rear latch, I installed a brake spring on the latch to pull the lever back to normal, that was easy

I have the same problem on my pass side front window...it's annoying whenever I have a passenger they just make it worse by trying to force it or they put finger prints all over the window by trying to push it down.

There is a "c" channel setup in there that some kind of a plastic square bushing rides up and down in to let the window go up and down.  The channel is metal, and over time, it gets enlarged/elongated, so the window slips front to back, then gets stuck in the corner above the mirror while trying to wind it up.  That's why hold it back while you wind it up tends to work.  That bushing has more movement than it's supposed to now because the either the bushing itself is worn out, or generally the channel is stretched.

I've heard of some people taking out that channel and squeezing it back tighter again in a vice and/or reinforcing it (weld some support to it on the backside of the channel), so it's a lot more snug against that plastic bushing i was talking about.

Your other option is to buy a brand new window regulator.

just unbolt the hinge and take them off! 

Pull the door panel, put the window part way down so that the two screws that hold the window to the channel are visible/accessable. Loosen the two screws, push the glass into the rear track as far as it goes and tighten the screws back up. Put the door panel back on and it should work now... I've done this to both of my Trackers and the window goes up and down just fine from the crank.

I think that there are several possible causes.  One of them is dirt and oxidation building up in the window channels.  You can try sprayin some silicone into the channels to lube things up.  Worked great for me and a bunch of other folks too.  If that's the problem (no guarantee) you won't even need to pull the panels.

Most window channels are felt and lube will cause them to gum up over time, possibly making the matter worse down the road. I have had good success with cleaning them really well with original formula armor all. Of course it's usually the front edge of the window that gets the stickiest, and about the only way to get that section really clean is to carefully pull the felt channel out of the door(with the window all the way down) or pull the panel.
