Wow thank you for making this video I am working on my 76 Grand Prix and I have video suggestion. Can you make a video for relpacing motor and regulator. I am planning on replacing both the driver side and passenger side with a kit from eBay … thanks

[@g3garage]

Not sure if I can help with the regulator replacement. The aftermarket kits a quite a bit different from the factory GM stuff and have not had a chance to work with the new aftermarket kits. Thanks so much for your comment.

[@Lynnjohnsonmuldokken]

when you were testing it did you ground the body of the motor? seen alot of techs I worked with bench these and not do that and think the motor was bad.

[@g3garage]

Yes, it was properly grounded. See the 1:20 minute mark in the video. Thanks for your comment.

Do you know if on a Manuel regulator if the small gear that’s spinning from the hand crank can be bought an replaced

[@g3garage]

No one that I'm aware of reproduces the regulator or any parts inside the regulator for these vehicles. Your best bet is to find a good used regulator and replace your broken one. We have several in stock and our website that we sell these parts on should be functional in the next couple of weeks. You can contact us on the website g3garage.com or send an email of the details (right/left/2DR/4DR, etc) on the part(s) you need. Thanks for your comment.
