Rear Fog Lamp Not Working

[johnson293]

After a few foggy mornings, and having to use my fog lamps, have realised that my rear fog lamp isn't working. Fronts work fine, but not the rears.

Have changed the bulb, and its not that, infact have tried 3 different new bulbs, and none of them worked. Just tried a tester, and there seems to be no power to the bulb holder either.

Had a look in the fuse box in the engine bay and couldn't see the fuses for the lights (any of them) on the diagram.

So first question, is the rear fog lamp on the same circuit and/or fuse as the front fogs (or any other lights)? All other lights (Head/side lights, front fogs, tail/brake lights and reverse lamp) are working.

Secondly, could this point to the light switch itself? The rear fog light on the dashboard illuminates when you switch it on, which maybe suggests that the switch is ok?

Beyond that, I'm hoping its not a wiring problem.

Car is due an MOT in june, so have time to sort it, and obviously want it done before then.

Cheers for any info/advice.

Try cleaning the pins in the bulb holder that's what happen to mine work ok after that

Just had a look at this again. Turns out it was slight corrosion on the wiring connector, that the bulb holder connects onto.

Quick clean and spray with WD40 type fluid, and the lamp is now working.

....Just as all the Bl**dy fog has cleared up here! :P
