Just heard a loud pop (sounded like something hit the drivers side door) then a few minutes later the driver's side window rolled down (by it self)..... I pulled in a parking lot and heard a pop on the passenger side and couple minutes later, the passenger window rolled down (by it self). Neither window will come back up! When I operate the switches ... I can hear the motor/s operating. I was not operating the windows when they all of sudden when down .... we have had several days of 105 degree plus temps lately ? Has some broken on the window control arm and how hard would it be to repair this myself???
