Lots of posts on replacing gears/plastic dowels. I've done all of that along with cleaning/lubing regulator(s). The issue is both door motors struggle to get the glass back up... barely makes it up to the top. New motor choices are not encouraging and I'd really like to keep my original hi-torque motors.
Has anyone changed brushes in a weak motor successfully? Did it bring back the strength?
I haven't opened the motors up yet, but suspect the brushes are worn down.
Suggestions welcome!
