Lat night I hoped in and started the car to find that ALL my lights did not work. Checked all fuses, all ok. No dash lights, no headlights, no interior lights...only the SES lights and such worked on the dash with the key on.
The radio didn't even work.
After trying different thing, and then tapping around in the head light switch everything came on and worked fine.

Is there some main lighting power wire that goes thru the headlight switch since all of the dash lights and radio lights dimmer etc go thru the switch??

The turn signals did work, both in and outside when this happened.
