5th gen Montes tend to be notorious for window problems. Mine intermittently won't go up. Then off of a sudden it does. Day last week, it was longer than normal. So, I did what we Italians do best...use blunt force on the door, and I put about a 5 inch crack in the plastic, and the screw hole at the top (behind the outside mirror) is cracked around about 50%. LOL. Oh well. Most of the crack is hidden by the dash, when the door is closed. I'll eventually replace it, not in a hurry now though.

 

that sucks man. could be worse though, my drivers side window track & motor fell apart in the middle of august, and my car's got no A/C, and i had to commute 35 miles with it to work during a 95*+ week with the window held up with a 2x4 untill i could get to the junkyard and get a replacement. the car suffered a few kicks and punches that week, lol.

EDIT: too bad it wasin't you're passenger side, i just remembered i've got a spare passenger door panel sitting here

 

my drivers side window is terrible, i always tell people its half manual. I have to help it up and down. Maybe some day i'll get it working right

 

mine has a dent in the door were the window rail is at mine would probly work well after i pull that out, we all got issues

 

I think GM had some issues in the late 90s because my 99 venture drivers window was junk too. the tracks were held in place by metal strips that bent after a while. You had to push it half way up by hand
