White 'Highway' strip lights in door panels

[Conquistador]

Morning all,

Long time lurker, first time poster so I hope somebody can give me some help with this small problem I've had for a while now.

Under the 'background lighting' section on the MMI, there is a 'highway' setting (along with city, cockpit and rear) which switches on strip lights in all four door panels. My passenger's side door light has not been working for a while now but all 3 other doors are.

Its just annoying more than anything as my eyes keep getting drawn to it and I wonder if it can be fixed easily. I quite like the ambient glow on a dark motorway run!


Hope somebody can help! Many thanks

If I haven't explained it very well, here is where they are located...
