I have a window motor that has stopped. Does anyone know if the 92-99
Bonneville window motors have three plastic bushings?

I have owned Fords which had the bushings disintegrate causing the
motor to stop turning and I'm wondering if the Bonneville motors have
basically the same mechanical defect with the bushings.

I have a 1991 Bonneville driver door window motor in pieces right
now......Do you mean brushes by chance? There are no plastic bushings
that you speak of, at least not in my 91 there aren't.

GM motors have two brushes that contact the armature. Mine were worn
down to the point there was not enough pressure applied to the armature,
but the culprit might end up being my express down module. Its the
original.

One of the Goodwrenches at a dealer I go to suggested disconnecting the
hot wire going into the module (there are four wires) that controls the
express down, then and see if the window motor runs.

You have to leave the wireharness connected to the module, because the
window motor power source still comes throught the module and so does
the ground. The express down module is the black box bolted the the
window motor.

Due to my schedule, I wasn't able to try this yet, but with the new
brushes I got from ACE Hardware (of all places) and this latest trick I
learned from the GM Goodwrench the motor will probably work again.

This motor was replaced in 1998. It was stopping and starting
sporatically. Same goes for lately, but I wasn't paying attention if the
express down feature was working.

Good Luck,

I dismounted the window motor and found that it was binding for some
reason and works fine after removing and replacing.

I looked at the window motor and it's a sealed unit. If it was dead I
would have pried it open and probably found bushings similar to this
used on Corvettes, Fords, and numerous other window and headlinght
motors:
