sounds like you need to replace power window master switch
Blown fuse in the fusebox.
try a stronger fuse, if that doesn't work then maybe your window motors are bad ?
fuel gauge not working and power windows and radio.2004 mercury mountaineer.
the relay switch has gone bad or the motor is burnt out
the motor for your power windows is shot, or your wiring is gone
check fuse. they are all conected.
If all the windows quit working you need to look for a blown fuse in the fusebox.
Probably
Check the fuse.
Blown fuse.
Could be a fuse if both stopped working. or a wire ,both windows are hooked up to same wire.
Check the power window fuses and the relay first. If all of the windows do not work then it is a power problem with the whole window system.
