recently tinted my front fog lights and they worked fine for a few hours but now I cant turn any of them on (front or back) also I get no little yellow light on the side of the switch either
, ive checked the switch and its good, I tried bypassing the switch with a bit of wire and can confirm that the switch it receiving 12v when I turn the headlights on,
ive checked fuse 6 (15A) and its fine because I had an issue with it blowing due to a short inside the foglight housing itself,
ive also checked the very bottom left relay for clicking and it does ( I also swapped it for another relay and that also clicks)
for whatever reason I'm just not getting 12v actually at either fog light housing connections front or back,
kinda stumped now,
anyone have a suggestion?

Re: no power to any fogs
check the connection under the expansion tank.
2 wires come out of the bulkhead and go into a connector plug under the expansion tank where it splits into 4 wires going either side of the car.
its a white chunky plug from memory and a bit of a wotsit to get apart but thats what i would check if it has 12v

Has 12v, sprayed it with contact cleaner but still nothing, will do more multimetering weather permitting

so you've got power getting to the switch, but did you check that it is then leaving the switch when you switch it on? if both front and rear have both stopped working, then the switch must be the most likely contender, as past this point i can't think of anything that would effect both front and rear fog lights.

Re: no power to any fogs
The relay would affect both front and rear too since it provides power to the switch.
Try removing the white/yellow wire from the switch - this is the power TO the front fogs - and applying 12v.
If the lights work then it's switch or relay. If they don't it's connectors or bulbs.
Also, Fuse 6 is only for the front fogs. The rear fogs have a separate fuse on the top of the fusebox with grey/white wires coming out either side.

Re: no power to any fogs
ive checked the switch with the continuity setting on the meter and apparently its good
ive also tried jumping the connections on the switch plug with some wire, no dice :/
i seem to also have no power at the fogs fuse when the switch is off and 12v when the switch is on

Re: no power to any fogs
That’s sounds a little strange... I may be and probably am wrong but surely the fuse should be before the switch lolYolandi2 wrote:ive checked the switch with the continuity setting on the meter and apparently its good

My only suggestion would be what your doing work from battery back. I’d suggest checking voltage rather than continuity though just because it gives you an idea if you have a short and loosing voltage somewhere.

Re: no power to any fogs
Always test a loaded circuit, just because you have continuity it doesnt mean the circuit can carry a load. Easiest way to do this is with a test light (Super cheap and very useful tool)
