If they move slowly but work in both directions, spray the rubber window tracks with Silicone Spray Lube. It goes on like water, then evaporates leaving a lot of "slippery" behind.

I did try this, how ever they have all now quit working all together, don't even make a noise now. I will be taking the front pass side apart today, just to investigate further. I am hoping that its just became seperated from the motor. LOL I can change out any part of a 13 ton Army track vehicle, any car motor, or anything. But this has given me fits. Thanks

Hold on. Lets think about this logically. If all of them quit at the same time, look for something they all have in common, and that's not any one motor. Given the history of moving slowly, look for things that restrict current flow. The most common thing would be a fraying wire between the driver's door hinges. The 12 volt feed wire goes to the master switch. If that one is broken, none of the windows will work from the driver's switch or from the door switches. The same is true of the ground wire. All of the motors are grounded through one of two circuits in their door switches AND the driver's switch, then through the ground wire between the driver's door hinges.

From the driver's switch assembly two wires go to each door. If one of those wires were broken, only that one window would be affected.

Besides broken wires, the master switch could have a burned contact. That is relatively uncommon. The clue would be the driver's window would still work fine because it isn't controlled by that master switch. Only the other three windows would stop working. Depending on the car model, if the master switch was defective, the other three windows could still work from the driver's switch but not from the door switches. On some models a bad master switch will make the other three windows not work from both the driver's switch and the individual door switches.
