The two passenger side windows have no problem going down but frequently they won't come back up for several minutes or sometimes hours, regardless of how many times you push the button. I noticed it first on the front window and thought it was the switch but then noticed the rear window doing the same thing. When they finally go back up it is in one of two modes. Either they go up about a quarter inch with each touch of the button or they only go up in the non automatic (one touch) mode only. I guess my first step would be replacing the switches. On this car all four window switches are on one switch set, they have to be replaced as a unit. Anyone got any other ideas. What would cause both right side windows to act the same way? The battery had been disconnected and I thought they might be out of sync but I reset that too.
