Can you tell me how to fix rear power window on Cadillac?

Answer by  wildwittedwolf (6)

Check to see if you are getting power to the window motor and switch. Process of elimination to determine if either is bad.

More than likely you are going to have to take apart the door to get to the window gears that pull it up and down. they could be broken.

You're going to need to fully replace the motor. Opening the door panel, replace it with a same model power motor.

Well first check the fuses. the one that controls the back window. Check your motor on window that is not working. Like when you push power window does it make noise and not come up or is it dead no noise. You may need special screw drivers and tools .But take the door panel off and there it is.

First confirm you;re getting power. If not, new electric window motor. Take off the door panel or metal button panel depending on year, and swap the old for a new.

It is most likely your regulator. You'll need to take off your trim panel on your back door and repalce the regulator, which you can likely but aftermarket at NAPA or O'Reilly's, or even a used one from a salvage yard, or of course from GM if you are willling to pay for new OE parts.

Use a voltmeter to check the window switch to make sure it works. If so then replace your old window regulator by taking off the door panel and unbolting it.

Take apart the door to get to window gear that lets it up and down. Gear or motor could be broken, you'll have to replace either one with exact model.
