2002 bonneville windows dont work - Pontiac Cars & Trucks

you have a worn-out electrical switch somewhere that is not opening/closing properly. find and replace, check your wiring harness and ground points

they dont have a fuse they use a circiut breaker

check the fuse, check the connection, check the switches and the remote

You will need a new window regulator,the cables have likely broken.There will be a few hidden screws behind pop out covers,the panel will then pop loose from it's plastic clips.

I doubt it, all the windows should work off the same fuse. I would be more inclined to think it might be a wiring problem, a broken wire or a connector come loose. Check the wiring that runs from the door pillar into the door and try trace the wiring back to where the rear harness connects to the front harness.

sounds like the bcm (body control module)

Do you hear any humming when the button is pushed? or any noises? If you do, then the Regulator is broken, and will need replacement. I would recommend getting the part from the dealer, Aftermarket China parts are ****. (dorman)

A bad ground from the battery. Clean battery cables and replace bolts, check alternator for output.

Consult you manual for correct fuse applications and schematic for correct locations for your non-working components. Possible blown fuse.

I had the same problem with one of my back window with is seldom used. The motor are using brushes to make contact with rotor. I took the lining of the door off then gently tap on the motor while trying the lower/raise switch. The window start to work ok. I try to operate the window more often.
