Window Help 2002 GT Convertible

[97JF]

Hi all, I may be going to look at a 2002 GT Convertible that's for sale, the seller says the driver's window sometimes comes out of the rollers, is this a big deal to fix ? Any idea how to fix? I assume the interior panel will have to come off? Thanks

I just picked the car up, the window goes down about half way then it comes off the rollers, to get it back up you need to kind of pull it up in to position then it will automatically go up
