Any codes or warnings on the dash?

Hello thanks for reply.
No none at all. All working. Says door open boot open all good.

I would start with checking the connections on under dash wires. I have had more than one occasion of hitting them with my feet and disturbing the connections. With size 14 feet I have had to purchase Vibram five finger running shoes to keep it from happening when driving.

turned car off last night in garage,all fine and working.went out this morning put key in ignition,no lights come on (ignition or panel light)but started straight away…Dark in garage so panel light usually come on.put side lights on and no panel lights come on,but other lights come on radio etc.any ideas could it be fuses??
