'95 Olds 88. Left front and left rear widows will not operate. Worked fine this morning. All the right side window work fine. I traced the power wires into the switch and things are ok there. I am getting power to the window motor, both up and down when using the switch but the motor dosen't make a sound (I pulled the door panel off to get a look see). Absouletly no binding in the tracks and everything looks OEM inside the door.. I have no problem putting in a new motor but it seems strange that both on one side would crap out at the same time. Just lucky or am I missing something?

With the distant rumble of thunder, I jumped out of bed rememering my window was down. Grapping my plastic sheet and duct tape I sping into action to cover the window before the storm hits. Just for grins, I pop the key in and start the car and hit the window button, the window smoothly rolls up!? I hit the back window button and it works fine. I play with both windows all the way to work and nary a problem. Now I am confused.

Chances are the brushes in the motor are shot. I just did my wifes window motors. You should be able to get new ones at www.rockauto.com
