The passenger side window has been acting wacky for a while. When I lower the window and then raise it, it will go back down about a third of the way. Also, those windows also have an automatic lowering mechanism when you open the door so when you close the door, the window raises automatically to create the seal. The passenger side has stopped doing that. The drivers side has decided to work only when it wants to. If it is stuck in the up position, I can give it a wack while engaging the switch and it will go down. As long as I don't let it go all the way down, it will go back up with no problem. If it goes all the way down, same procedure is done, I just give it a little wack in another spot on the panel. I have already replaced the relay switch and that didn't fix the problems. I just have a hard time believing both motors have gone bad. I have heard those windows can get out of sync. Can I fix this myself?
