Fog light wiring issues!
Fog light wiring issues!
For some reason my rear fogs don't work, the light on the switch won't come on, and I can't for the life of me figure out why. Tested bulbs and both fine.
The weird thing is, when I remove this fuse (driver side footwell, second down on the left, fuse puller on it in the pic) which is labeled "TAIL" it kills the rear light clusters BUT the fogs will work on and off on the switch. If I put the fuse back the rear lights come on and the fogs stay on until turned off, once off they won't come on again!
I have followed the wiring back from the bulb holder through the boot arm to the boot and back through the rear seats to the front seat (boot build out, rear seats out, MASSIVE task!) but everything I can see looks fine and hasn't been messed with. I suspected a bad fog to brake mod but can't see any evidence of it.
A couple of pics just because I have them:
I found a lot of wires here, but none seem to be related to the problem!
There was a bodged fog to rear light mod, with added bulb holders inserted though holes drilled in the back of the fog light, and wired to the number plate lights. However as this didn't touch the bulb holder or the supply wires for the actual fog bulbs, I didn't think it could be the problem, but removed the whole lot anyway so it back to stock.
Any ideas, anyone? I'm stumped!
Has one of the fogs or tail wires been grounded to earth? I found in our car that all of them work on some weird switched negative. Might be a mod in any of your lighting system causing it, even interior lighting in that case?

The diodes could have broken down. I'd disconnect the fog brake mod to be sure.
The alternative is the fog switch itself maybe?

there looks like there is a relay pack installed in one of the images this one
It could be that they have not gone down a diode route for the fog to brake option and done it using relays if they have and one of these has failed this could be the issue ?
Try tracing these wires to see if they match up ?

thats a nice boot build!
