Fog light problem (Urgent for MOT)

So the 90 had it's MOT today. Failed, but nothing major: Bearing play (hub nut needed tightening), uneven brakes (bled and cleaned). However the Fog light doesn't work. Last year I had the same issue although it just turned out to be a rusty spade connector. I again cleaned that up and no light. Used the multimeter on it, nothing. So I automatically went and checked the switch on the dash, no light shows up on the dash. Took the switch out and tested the voltage on the connectors. Nothing at all. Check all the fuses, they appear fine. I am very much confused and I want my Landy Working for the LRO show

What's going on!?

Cheers

You did have the main lights on when you did the test? with voltmeter you can test if power is arriving at switch with column covers off [contacts are exposed]

Did you check the switch continuity with your mutimeter as well?

Make sure the switch is working.

On mine the fog light was knackered. New fog light all was working again.

Got it fixed in the end, first of all I wasn't dong it with the main beam on (stupid) and the terminal snapped off when I took the light out the second time. Soldered it back on and wiggled and turned the bulb (wasn't locked in properly) and hey presto! Though you have to use the switch twice to turn it off...
