Can someone plese tell me whats wrong with my Mazda Millenia? My first problem was the illumination of all gauge lights went out. The check engine,oil time and everything else on dash works. Then one headlight went out. A guy jiggled the headlight wires and it worked again for a little while. Now both headlights went out. high beams and turn signals and fog lights working. Auto advance suggested the dimmer switch out?

 

If the exterior running lights are also out at the same time the dash lights quit would be looking at fuses. Mazda often labels it the "TAIL" fuse for power to the dash and running lights. If running lights are all working and is just dash lights then the panel light control switch or dimmer would certainly be suspect.
Try a new headlight bulb for the lowbeams. Is the easiest and quickest thing to check and see if it is just a burnt out bulb.
