    Any recommendations, the drivers front headrest sometimes does not work. I am sure it's not the button which is at fault but some electrical loose connection from the headrest side because if I wiggle the headrest then it more than likely works for some time.

    Any hints?

    Regards.

    It will probably be the connector to the motor inside the seat.
    The cable going into the motor is not supported properly and the solder connections on the motor crack.
    Relatively simple job to fix if you are handy with a screwdriver and soldering iron.
    Have a look here:

    Mine was the same as yours and it took less than an hour to fix.

    Thanks, I think your right. If I sit in a different position then it works fine. So it must be a loose connection. Just wish I could fix it without taking the seat out. I may have to use an indi to have a look then if I can't do it myself.

    Thanks.

    You don't have to take the seat out.
    Removing the seat back is only a case of removing two screws at the bottom. 5 minute job.
