Hoping someone will have an idea of the best place to start looking for a fix for this -

Fuel light is constantly on, even with fuel in the car. Speedo isn't working, but rev counter is. Econometer isn't working either.The fogs won't work, and the dash light to show they're turned on isn't coming on.

Can't say when this began - had only been moving the car around a bit so never paid attention to the speedo or tried to stick the fogs on.

Have run the instrument cluster test and they're all working as they should. All fuses are fine.

Any ideas?
