1996 Other Ford Models Dash board and rear night lights

I am hoping that you could tell me if there are any faults that might help me fix my lights?
The dashboard lights and rear night lights just stopped working yesterday when I stopped to pick my son up and they were working before I stopped.

I have had a new switch arm put on 3 months ago and that seems ok and I have done a continuity test across all the fuses to make sure they are all intact but still no joy.

Can you suggest anything before I spend money I havent got at the garage?

I would appreciate any help you can give me in this matter.
