Gs430 Rear Tailgate Fog Lights Not Working

[GGMan]

Hi

Not long had my GS430 51 plate and just notice my rear tailgate fog lights are not working.

Press rear fog light switch, indicator comes up on the dashboard okay but no lights at the back.

I have checked the bulbs, they are not burnt out (but a new bulb just to make sure).

Fuse changed in fuse box under driver side still no lights (main beam is switched on)

Is there something I missed?

I just spent a hour on google and here but I have not been unable to find any good info, so I hoping someone here can help?

Regards

Welcome to the club Gary, have you tried cleaning contacts in bulb holder?

Hi and thanks for the welcome.

I did take a look at the holders and the copper inside the bulb holder are very clean.

IIRC foglights do not come on with main beam only dip beam?

The switch goes through the body ecu and then via a relay (the relay is powered through the 10amp "Tail" fuse). The body ecu deals with the telltale lamp on the dash.

Do the front fogs work? They also go through the body ecu and another relay (again powered through the "Tail" fuse).

An ECU to control the fog lights, over engineering at it's best :)

Hi

Front fog lights are working okay.

Hi Gary, welcome to LOC. I'm in Washington, where are you.

Hi

Front fog lights are working okay.

I would check the rear fog relay in that case.

Hi

I live in South Tyneside.

TigerFish, could you tell me were the rear fog relay is located please?

Thanks

I believe it is in the drivers side relay block (drivers side footwell kick panel).

Hi

Thought I let you know I got fog lights fixed, £60 - took it to Car Electronics (as all above did not resolve issue and it was really bugging me) .

Issue was due to cables being cut (in the Boot hinge), as at some-point someone had tow bar on it.

Glad they are working now.

NB: Found the fuses for rear fog lights in the passenger side not driver side

Thanks to all for advice on solving issue.
