Hi.
The glass was left one inch from bottom; with my arm pushed it down with not much force by accident and the driver window stopped working. Did hear the motor not stopping. Reversed direction briefly to stop it, and did.

Removed the whole thing; the mechanism is like new, nothing worn/rusted/bent, rollers fine and lubricated.

Powered removed, all the regulator moves just fine. Reinstalled, has no force to move the glass. Is there a clutch inside the motor gearcase that gave up ? Is the clutch adjustable ? Do I have to replace the gearcase, the motor, both as an assembly ?

Edited: Found the problem. There is no slip clutch. The gearcase couples the output gear with a cheap black plastic wheel. Broken.
Anyone with a burned motor behind the spider webs that I can buy the gearcase?
