It sounds like the track that the window rides in needs to be lubricated. I know that there is a specific type of lube used for this but I'm not positive what it is. I suspect it's a silicone grease or something like that, something non-oily. There may also be a problem with your window mechanism slipping. On my truck the window motor will keep pushing the window up even when it's up all the way, but on my truck the gears don't slip like yours. The sticky track may have worn the gears out. Try taking the door panel off, using some silicone grease on the track, and replacing the motor gear. Good luck.
