**** UPDATE ****
Still no headlights! :mad:
Since the last post I've replaced BOTH the dimmer switch and headlight switch. Still the lights don't work. Same symptoms.
Interior dome light works, park lights work, interior lights work (albeit sporatically). Should I now just consider replacing the entire underdash harness? There seems to be nothing else left to do (other than check the sockets at each headlight bulb to ensure electrical continuity - am I'm both headlights did not burn out together; dim and bright).
