I know there have been a few threads on the power window regulators recently, but after receiving some PM’s about replacing the window regulator, I decided to create a write-up, as promised in this thread.
This write-up details the problems that have been reported to occur with the front power windows, and the solutions to those problems. Also included are part numbers and temporary solutions to keep your window closed whilst waiting for parts to arrive.
Hopefully this is helpful to those wishing to carry out their own problem diagnosis and repairs to save a few bucks.
I will post a print-friendly pdf file here when the hosting site I use is back up and running.

It is a known common problem that the 9440 9-3SS power windows, particularly the fronts, are prone to malfunctioning beyond repair (without purchasing new parts). If you’re unable to claim the malfunction on warranty and your dealer won’t cover it, this is a guide to help you in determining where the problem originated, how it can be fixed and the parts you’ll need in order to carry out the repairs yourself.
There have been reports of this problem originating in a number of areas of the power window design; some are more expensive to repair than others. These include:
· The clamps that grip the window glass work loose;
· Malfunction of the window lift mechanism;
· Malfunction of the motor/gearbox assembly.
To properly diagnose the origin of the problem, you will need to expose the workings of the power window…
