Electrical problem
2005 Buick Terraza 6 cyl All Wheel Drive Automatic 128, 00 miles

The rear power vent windows (both left and right) and the rear wiper motor have stopped working at the same time. What can I check for the problem? There does not seem to be a fuse or rrelay listed in either fuse panel/power distribution center for either of these devices. Is the a harness connector that controls both that could have come loose, or a power relay associated with borh?

More than likely it is a coincidence that all the motors have failed at the same time. It is common that the rear wiper will fail. I would replace that. The 2 side motors are common to fail as well but I would check power and ground at all the motors just to be sure.
