Headrest motor adjustment
The headrest in my 94' e320 wasn't working so, after searching the archives, I got the seatback off and found the offending part. The white plastic gear assembly broke apart. After examining the part, it appears that the motor overpowered the gear assembly causing it to separate and crack. The question is, is there a clutch type adjustment on the headrest motor to stop the gears from turning when the headrest is at either limit so that this will not happen again?
