    Nice write up Gary, for reference the motors are interchangeable albeit the colour codes are different.

    This is a pair of motors. Can anyone identify which is the forwards/backwards and the up/down one?

    I think the longer cabled one is the front/back motor

    Forwards/Backwards = Right
    Up/Down = Left

    Notice the coloured connectors on the end of the looms, black and white, these match up with seat loom.

    Looks like we have a consensus of three then. I'll update the image in a bit.

    My drivers seat forward/back motor is pretty noisy. Not sure if it's the motor or another part. Anybody have experience of noisy motors failing?

    @DivideBYZero If you look at gary's picture in the first post there are two drive spindles coming out of the motor, these drive spindles are enclosed by a plastic tube. I bet one if not two of the spindles are slightly bent and are rubbing against the plastic tube which causes a loud noise. To test this put your hand over the tube/s and move the seat backwards/forwards you will feel if they are bent. You can straigten them again without removing them from the car.
