Hi Guys,

I am trying to find a part for my 89 M635csi. The drivers headrest will not move up and down, it is a common problem with sixes. When you press the button to move the headrest up and down you can hear the motor spinning but nothing happens. There is a worm drive which connects the motor to a ratchet type assembly which in turn lifts the headrest.

I have tried to order the part from my local BMW dealer, it is about £120/170euro but they are telling me that it is no longer available even though it is still listed as available from OEM. The part is listed below and it is for a memory sport seat.

I would be most grateful if someone could point me in the direction of a second hand one.

If your headrests fail to move up and down but you can hear the motor turning, there is a potential fix which is very simple. The way the motor is located in the seat back, the cable hangs more or less vertically. It appears that the cable "shrinks" and when it does it follows gravity and settles in to the motor end and coming out of the headrest drive. The easy fix for this is:

1) Remove the seat back by taking two screws out of the bottom corners of the seat back UNDER the seat back.

2) Slide the seat back down to disengage the two clips at the top and remove the seat back. The motor is now exposed.

3) Remove the motor from it's bracket allowing removal of the cable from the motor.

4) Cut a piece of coathanger wire 1/4 - 3/8" long and drop it into the motor sqare hole drive. Make sure there is enough of a gap between the end of the wire and the top of the square drive for the cable to make a good engagement with the motor. Shorten the wire if necessary.

5) Spin the cable, pushing it upward to engage the headrest drive, making sure enough sticks out the bottom end to engage the motor drive.

6) Re-assemble the motor into the seat back and test for correct operation.

7) Re-install the seat back in reverse order and proceed to do the other one.

8) Volunteer to help a friend whose headrests are malfunctioning and be a hero!"

Thanks very much, I will give it a go. Will let you know how I get on.

Will eagerly await your reply. My headrest/s also do this.
