Operating my power window
I have my 02 Chevy Malibu passenger side front door on the bench and I want to power the window up so that I can remove the door lock. I'm in the process of replacing the original door because it was damaged.
My Question is can I use a small 12 volt battery to operate the window without the door being attached to the car. I am worried that it won't be grounded as it would be when mounted on the car? hotpipes Last edited by hotpipes; 03-22-2017 at 09:21 AM. |

Re: Operating my power window
Sure- the motor is reversible, just jump positive to one terminal of the motor and negative to the other, then reverse the polarity (swap terminal leads) to reverse motor direction if needed.

Re: Operating my power window
And there is no concern that the door is not attached to the car for a good ground?

Re: Operating my power window
No concern with door being ground. You are attaching a ground lead when you connect the battery. Also i believe if you look close the window regulator motor is on rubber mounts the the bolts go thru. Not sure on your model but i have bench tested alot of doors without them.on the car for door lock and window motor function befor reinstalling the door.

Re: Operating my power window
Your "ground" is coming out of your test battery negative terminal when bench checking- forget the car battery ground- besides car ground flows reversible through motor itself when activated- having nothing to do with vehicle ground.
