Disco 2 Dash back lighting and switch illumination issue

an irritating issue.... especially at night !! All started from replacing a blown glove box light, replaced the lamp and ever since then the dash back light and switches illumination (hvac illumination etc etc) does not work... ie when turning the headlight switch to on, clock doesn't dim and there's no backlighting on the dash ie fuel, temp revs , speed.
checked fuses and everything seems ok, had a spare headlight stalk and replaced that thinking it might be an issue with the stalk...
any pointers would greatly be appreciated.

but the glovebox light you fitted works alone ? if not double check fuse F33 and if it's 100% good check if there is voltage on it

Just for fun, my fuel gauge light stopped working last summer, i.e. 2023.
Recently it has suddenly started working again.
And I too have no idea why!!!
