05 Almera fog light not working

Wife’s 2005 Almera 1.5L hatch just failed the NCT because of a non-working fog light.
Neither the fog light nor the yellow display on the dash are working.

I swapped the rear fog bulb with a working indicator bulb, but that’s not the problem
I checked the 10 amp fuse in the engine bay fuse box, but that seems ok too.

I think I found a relay for it, beside the fuses in the lower dash area.
There seems to be 3 blue Hella relays and I think it’s the top one, as I can feel the click in it when the rear fog is activated.

Access is tight, without removing some of the lower dash and I’m not sure if the relay just pulls out, or if I need to undo a tab somewhere on it.
I suppose it could also be the switch on the stalk or a wiring issue, but I’d like to swap out the relay first.

Has anyone had any experience with this problem?

Thanks.
