07 GT Fog Bulb failure

Hi guys,

New on here, I have searched and found some tips on fixing the problem but to no avail.

I get a failure warning that left rear fog light bulb has failed and the rear left fog bulb does not illuminate.

1. Bulb checked- tested working with a 12v supply

2. Contact raised with a small screwdriver to ensure good tight fit.

3. Contact in removable harness sanded to remove corrosion.

4. Fuse in Fuse box checked-other fogs work so it cannot be that.

I still get the warning!

Any other rabbit ye can pull out of a hat for me?

Is it possible to multimeter the end of the plug/harness to check if voltage is received at that end?

I presume the rego plate lights, and reverse light work? Do you have parking sensors, and do they work?

I'm struggling to remember, but I expect all of these have wires in the same wiring loom that passes from the cabin/interior, to the exterior, to the bumper. Maybe the wire is broken somewhere, like where it passes out of the cabin.

Thanks for the reply, will put a multimeter on it this morning and follow the wiring loom as far as possible to look for breaks.

Yes have parking sensors-yes they work.

Reg plate bulbs work.

Reverse Light works.

One thing I did notice is a bunch of 3 or so wires run across the top of the exhaust backbox. Very odd they should do that.

Has any other gt owners noticed the wiring loom for the rear left fog lamp is hanging down around the pipe?
