Morning Angie,
Hope all is well with you. Yes you have the aftermarket auto headlamp switch.
My initial guess is either the switch has unfortunately given up or the switch housing is rotating inside the fascia.
Can you confirm that the central chrome surrounded switch rotates independently of the icon ring (with the work auto on it), does the icon ring stay in place when the switch is rotated.
I might have a spare auto headlamp switch here but you could also easily go back to the factory standard switch and fascia.
I notice you’ve not got market access on here but if you was to upgrade you’re account then finding a standard replacement part would be fairly easy. The actual swap is quite simple and more then happy to discuss it over PM should you wish.
Kind regards,
Tom
