pass window has trouble going down, and wont go up

[TurboDomestics]

well I think I fixed it.
I sprayed some Silicone, on the tracks and that helped a little bit, but it still couldnt go up by itself. So I took the door panel off, and I noticed that the track thats towards the back of hte car was rusted like crazy on one side. So I took my flat head screwdriver and scraped all the extra rust off between the metal track and the rubber weatherstripping (For about 30 mins). And now it goes all the way up and down, by itself, but it still goes up slower than it goes down, but it works for a 4$ fix!!
