When I try and put all the windows up at once with the all windows button, The passenger window goes up half way then stops, but all the other windows finish going up. Then I have to push that windows individual button to make it go all the way up. What does everyone think the problem is?

might have some dirt in the window track causing it to stop...

a likely cause is a window motor starting to go bad, does the regulator make noise when moving?

Nope no noises, I think amancuso is right I need to clean the track.
