When I operate the light switch on dash nothing happens - no panel lights , no side lights , no headlamps popping up . All worked ok before and will go have a look with a multimeter tomorrow . Suspect switch as there are 6 or so independent fuses protecting individual items and doubt they have all failed at same time .
Hazard lights work off their switch , turn indicators work off their stalk , reversing lights ( backup lights ) work when reversing .
What shall I try ?
