Disco 4 Mirror light and camera problem

Hi there,
I'm new here - thanks for letting me join!
I have a 2011 Disco 4 with the puddle lights and cameras on the wing mirrors.
The driver side mirror light AND camera don't work.
Is this likely to be the same problem - ie a dodgy earth or something? Is it common?
Where should I look?

Many thanks in advance.
Cheers, Grant

Hi and welcome , if u don’t mind me saying plse pop over to the introduce section as always nice to have some background with new members

Ref ur door mirror would first check the fuses , then get a wiring diagram and remove the door card

With a multimeter check the relevant wires to check if u have power and earths

Not 100% but wonder if the mirrors go through a module

Hope that helps
