I have a failed driver seat in an 85 500SEL, neither the front to back motion nor the backrest is funcitoning.

I have had the backrest prob before and I removed the back panel, removed the motor and manually set the seat upright for couple day while I waited for the replacement motor.

On the seat, if I pull it, can I manually move it forward or backward with the motor still attached?

Thanks!
