Has anyone replaced the rear window regulator for a crank window. Mine went south and sounds like the wire is twisting and breaking in the housing. I took the door apart and see what I am in for, but not sure how to get the glass and regulator out and separated. Anything special to do besides push the white tabs on the track? Rivets to pop out or anything funky? Need to get this done. My son loves his window down and it wont roll at all now. I found the part for $50 so price is right.
