Citroën C3 front right hand blinker not working

[Nego2403]

Hello

The front right hand blinker on my Citroën C3 is not working. I've checked that the bulb is working and checked all fuses. Do someone have the wiring diagram for the headlight so I can check if there's power on the pin for the blinker? If that's not possible what color is the wire for the blinker? The VIN of the vehicle is VF7**************[VIN obfuscated, can be read by forum staff].

Best regards
Nikola

Does anybody have the wiring diagram for this?

2615 is the Right hand Headlamp, with indicator on pin 5 (288), ignore colours - they change. The earth is on pin 8
The same is for the Left hand headlamp (2610), but the wire id is 287.

I can't see a fuse for these, so it may be an internal relay in the engine fusebox shown below:

It may be worth checking the earth wire, (MC37) shown below, from Pin 8 on the Right headlamp, but these share the same earth point, so could only be the specific Right Hand wireor earth, unless it is internal to the fusebox.

Thank you very much! Helpful as always How do the pin numbers correlate to the plug? Is the first pin to the upper most left? The plug has two rows of pins.

Also worth checking the bulb holder... Even a little corrosion on the contacts can stop the bulb illuminating and is, in my experience, a very common reason for failure so well worth a check...

Might be water ingress, like my tyres lol

Yes I checked this. The headlight is sealed and there is no corrosion on the bulb holder. I don't measure any voltage on the pin for the blinker. I've checked the ground and it is also good.

The pins numbers are marked on the socket / plug

Ohh okay thank you. It wasn't visible to me before I removed the plug

Are you getting a blinker output at pin 6 of the 28 way brown connector on the under bonnet fuse box?
Are all the other blinkers working at the rear & side.
Is it the same if you operate the hazard lights?

What connector are you talking about? I can see three large connectors at the fuse box under the bonnet.

All other blinkers are working also when the hazards are on.

Its one of the 3 large connectors. The colours are on the underside of the connectors so you cant see the brown colour till you un plug it.
