Hello,
My MK2 fabia Dash cluster lights have gone off as well as the radio screen, so none visible at night. (radio visible during day)
Window switch not showing green glow either, I don't think.
I later realised that the rear tail light was out, so have now replaced...however no change to Dashboard.
Checked all fuses and none blown.
Main headlights work as does headlight dipping roller.

...any suggestings I could try, would be great

Thanks

It’s a fuse. One that connects to the headlight switch 

misterb, I placed a reply to the other thread you re-posted to. There can be an issue if you wipe or clean the dash pod and the electric/static charge puts everything out... 

If it IS this, disconnect the car;s battery for a short while and then start again. Best wishes.
