Headlight hight adjustment motor

Hello all my name is:Henrik
I have a: (, 3000GT, VR4, TT)
It has the following issue:
When i turn on my headlights and they pop-up, on one of the headlights you can hear the hight adjustment motor keeps running…the light makes a small click and the projected light from the headlight (on a wall) shifts a bit, and then the light is shifting position up again, until same click, and the light shifts down again…keeps running.

Seems the height adjustment motor is not able to find the home position.

How do i fix this ?
