Blazer/JImmy rear window regulator swap??

[superck80]

Hi I have an 89 Jimmy/Blazer and the regulator stinks. I replaced the tracks, the motor, the cable, and the regulator and it still seems that it isn't strong enough. It runs fine with a drill on the cable. Has anyone ever tried to put a suburban direct drive motor in place of the cable and motor?   ???I think it should work a lot better, but i do not know if anyone has been successful. Otherwise can anyone suggest a way to make the motor work better? It is slow up and down. Any help would be great thanks!


Something else i noticed about these motors-- If you hook the rear motor up to a battery charger on 12v, the motor will not turn. Are these motors 6v or 24v or something? is it possible that there is a voltage converter that is bad and that is why i am not running full power?

I just saw this, sounds like you are dropping voltage along the way. If you still are having problems let us know.

Wow, how did we miss this post?

I would definitely use larger gauge wire and maybe think about using a regulator as well.  That will help with voltage drop.  My rear window was slow as well and I rewired it with larger gauge wire and it helped a lot!
