Drivers window quit. Cable broke. Got new regulator assembly and disassembled the door today and replaced the regulator. Now it doesn't work at all. Other 3 windows work.

Removed the "black box" from the motor (the one that's just on the driver's motor. Jumper cables directly to inner terminals on motor and the motor turns. So, my problem is either in wiring or the "black box" which is part of the motor assembly. I have no clue how to trace the wiring in this setup. Am I safe to assume there's something burnt inside the box and replace it? Or is there something else to diagnose the problem?

Any help is greatly appreciated.

Did you replace motor and regulator or just the regulator? Did the motor work before replacement?

 

The motor was working when the regulator/cable broke. The window slipped down so I pushed it up and taped it there until I had time to fix it. The switch may have inadvertently been pushed a few times since.? I'm thinking either the switch or motor went in the meantime and I'm sort of betting it's the motor.? It's been taped for a month or more. The other three work fine.

Tap on the motor with a screw-driver handle and see if it runs.

 

The motor does run if I by-pass the black box. The box is part of the motor assembly, though.

Are the pins/connector in the pigtail making proper connection? And you are getting power to the motor? May be time to replace it.
