Very rarely before did i have the problem. . but now it's VERY frequent. Neither driver side nor passenger side switches can roll up the passenger window. It's almost like it's sticking inside the door. . then all of a sudden it will roll up and work... then get stuck open again and won't move. Could this be an electrical issue?or something inside the door itself... {BTW--this is on my 94' 2wd truck}
