Power liftgate grinding W166 ML350 Bluetech
I’ve got an issue with my liftgate, wondering if someone can provide some input. I recently had my rear windshield replaced and since then, My power liftgate is not working.
I click the button, there is a loud grinding noise, but the gate won’t open. I can pull it open and push it closed, but it’s extremely stiff.
So it sounds like the system is trying to catch onto a gear or something but keeps slipping.
Any ideas what could be wrong?
