my two front windows are fine...but the two rear power windows...when i open them they make a sound kinda like they were stuck to the weatherstripping but kinda not...(more like a car that was airtight, then suddenly opened)...and when the window reaches the bottom, it makes a big thump noise...like it has a lack of padding at the bottom of the door panel.

does anyone know how to solve this problem?

 

Try using silicone spray lube on the channels which hold and guide the edges of the glass. Wipe off any overspray which lands on a painted surface. If this doesn't resolve the problem you may have to remove the door trim panels to access the window operating mechanism for further diagnostic examination.

 

the windows aren't stuck....they go down very quickly...and i've done the silicon spray lube trick already. It's just maybe it seems like the mechanism that pulls the window down goes down too far...because i can hear a loud thump when it reaches it's lowest limit.

my friend though he broke up, but i just told him that it was normal.

help?
