My passenger side seat wont go forward or back after leaving the car wash the other day and I found the rear carpet jammed up in the seat track.

Long story short they dont want to cover repairs so I bought the seat motor for it and now it will just click when I move the switch whereas before there was no noise. I work in a shop but the techs have no experience with the mercedes systems.. Any ideas?

Happy new year lmao

Did you try bench testing the motors?
