Several years ago my drivers door shorted out. Not a complete meltdown, several wires were damaged. I discovered that after years of use the insulation had rubbed off of the wires where the harness goes through the inner door sheet metal. Which caused the short.

That's the most common failure mode. The other is that the brushes in the motor wear out and cause a short in the motor.

Joe, You mentioned the 2nd most common issue is shorted motor, I am also working on a failed power window and want to bench test the motor. The motor has 2 connector terminals at the plug end of the motor. Would it be as simple as ground the assembly and positive to test at one terminal and then to reverse, switch positive to other terminal?
