some times i can not get the windows on both side of the ttuck to go
up or down email betonwill@yahoo..com
When they fail, do they fail at the same time? And then do they start working again together?
I would focus my attention on the master window switch on the drivers door. However, you could also have coincidental failure of window motors on various doors. A circuit test is in order to find out if you have power and ground going to the motors when the failure occurs.
