My window
 

The window in my 02 Mustang rolls up about a 1/4 of an inch to high. It looks like it's just the front part of the window thats trying to roll up to far. Anyone else ever have this happen?

Yeap. Its either the stops are not set correct or broken or most likly the glue that holds the window to the support has come undone. Either way you need to remove the door panel and weather strip and take a look in there.
If its the glue then you will need to buy a new window. Another way to tell if the glue has come undone is to see if the window seesaws back and forth.

Found a little time to take the door panel off today. The front stop came unglued. Does anyone know a ball park price for a new window?

Paid 225 installed about a 2 years ago. that was for same day service on-site and I made him vacuum the glass out of my car (which I'm still finding to this day). Someone broke in and stole an empty laptop bag.

it will run you around 500 at the dealer to hire some car glass company that can do it for you for 200 bucks. when i found that out i was pist....I was hoping for some oem ford stuff....what was i thinking.

that happened to me but on the back of the window, the glue had come loose and pushed the window upwards. everytime I closed the door it would hit/scrape the roof area right above it. I ignored it until one day my window got completely loose and fell down half way, I could not roll it up or down.

the first time it happened i got it fixed by some mobile car window fixer guy for 60 bucks, he cleaned out the old glue and put some new glue. he did say that this fix would last me about 2 years because of this special glue from factory and that's exactly how much it lasted

the 2nd time i took it to the dealership ($$$tupid move).

get it fixed as soon as you can. and apparently there's no way of fixing it without getting a whole new set, the glue is some sort of Godly glue that can withstand extreme heat...blah.blah.blah!!!

good luck

Got the window replaced. It was $234.40 for the window and $30 to have it tinted. Sucks, but its fixed.

Thats pretty much average for price and yes dealers dont do window nor locks better to go directly to a window place or a lock place.
