I have a 2003 Outback and suddenly all of my instrument panel lights have gone out (except odometer light and PRNDL light). Along with these, the bright headlights do not work with the bright on switch when pushed forward, but do work when switch is pulled to flash them. The fog lights aren't working (but I honestly don't know if that has anything connected, as I never use them anyway). The over head light comes on with door opening and by using the light switch itself, but does not come on with the dash dimmer switch. I've checked the fuses and all is well. Any ideas of a source to begin my probing? Thanks
