OK back on topic, what Gussie was trying to say was that many of us have found that by widening the FRONT metal vertical track that holds the rubber weatherstripping, we can reduce and/or eliminate the binding. I messed with mine at least 4 times till I got it just perfect.
Take your inner door panel off (carefully), see instructions posted here somewhere if you need guidance on it.
Open/lower your window all the way.
You can pull UP on the front vertical rubber weatherstripping to give you best access to the upper portion of metal track directly. Pull up on it right by your side mirror and let the excess you pull up just lay there on the top of the open window. I even ended up pulling it up entirely, so the entire front metal channel was accessible. (You can also raise window, then just grab & pull rubber out/away from track to get it out of your way, but since it's attached to rest of the strip, it can be a bit hard to gain access to very upper track- which is where mine was binding the most.)
Then I used an adjustable wrench to reach through some of the openings in the metal door to reach the front vertical channel "or track" and pulled on the edges to widen it. I kept testing my window as I proceeded. The window glass will work normally even without the rubber weatherstripping in the track. No damage to glass either. If the glass still seemed to bind going up, I'd then target the area for further widening, knowing once the rubber weatherstripping is back in place, it would still bind in that area.
Some also then bent the small horizontal metal brace that secures the front track forward a bit. This further reduces the pressure and binding on the front/leading edge of the window glass by the rubber.
After I felt it worked w/o any binding, I cleaned out the front rubber track and then applied pure silicone spray, rubbed it throughout, then reinserted the weatherstripping. I used my hand stuck inside the metal hole to pull it down as I slowly lowered the window. Popped right back into the track easily.
I'm attaching a picture of Tim at SBC installing my metal brackets (see separate thread on that topic...you should get those for your windows if you don't already have them). I'll include them just because it shows the inside of the door and you can see the metal track I'm talking about. Or go to my gallery and look at the pics, look for the front metal track I'm talking about. Between that and getting the SBC brackets, it will fix your window problems.
edit....p.s.....hubby & I lived in Plano for 11 yrs, LOVE TX, we moved to Northern AZ about 18 months ago, boy I don't miss that heat! Whewew!
See the scratches on the burgundy vertical track, that's from my wrench grabbing it to widen. I've done more widening since pic was taken, all along up and down as far up as I could get the wrench.
This pic just shows you overall what the door looks like behind vapor barrier.
This shows SBC's brackets glued onto glass
