C4 Pic 2014 Exclusive (B87) - Wing Mirror Indicator Not Working

Post by zane2g2 »

Evening all,

Just a quick one (Hopefully :rofl2: )

My passenger side indicator light stopped working some time ago.
So... knowing it was a sealed light I purchased a new one and went about replacing it.
So I took the wing mirror apart in the normal way that is to replace the unit.
Put it back together & went to test it.... bosh.... still not working.
I've tested the old & new light unit, and they both work (Bang head against wall).

The thing is does anyone know why just the mirror light isn't working?
ALL of the indicators lights around the car work fine.

Cheers all,
Zane

I wonder if you have a multi switch on that door and if there are any faults with it. The wiring harnesses to the mirror go through the multi connectors in that area.

DO you know where there are any connectors on for the door or a wiring schematic for the wing mirror/ door?

you need some of the moderators for diagrams/schematics but, if you lift the electric window switch module out you see the harnesses. You probably won't be able to get much access but is worth a look before you pull door trim off to get access

The first place to check is the connection between the door and the A Pillar section where the wires are fed through. There will be a flexible protector that you will need to remove to check the condition of the wires as this is a common stress place for them to break or start to break causing intermittent failure of equipment like the mirrors, locking etc.
