hello everyone, i have just bought my 94 530I, and just found out the headrest do not work. when u try to move them you can hear the motor running but the headrest doesnt move. i searched and found the seat cable fix, my question is, i tryed to pull the black cord out of the top right motor but it doesnt seem to come out, do i have to undo the two screews that hold the black plate at the bottom, or do i just have to pull really hard.

by the way this forum is great, thanks alot in advance.
