Dimming lights and switches

[Andyman]

Evening all

Just noticed today in OH T6 Caravelle

The dimming wheel next to the lights switch doesn’t seem to do anything

Previously it would dim the lights in footwells and doorcards and the red lights on various switches

Also noticed that the electric window door lock and electric mirror switches no longer illuminate when the lights are on

Does anyone please have an idea, maybe a fuse? If so any idea which one

Thinking my solution may be in the hands of @Pauly or @Deaky amongst others

Thanks in advance

Hi Andy, did you get to the bottom of this fault? My dashboard and cluster illuminates, but both door switches do not. Cheers
