my dash lights recently went out, have checked all fuses, is it possible it's the H/L (combination) switch? any help or suggestion is appreciated.

OK.  Now (with the light switch "on") measure the voltage coming out from the dimmer knob, first try at both extremes of rotation of the knob.  If you don't get voltage either way, and in the intermediate positions, you have a bad dimmer switch.  You can try a jumper wire to ensure that the rest of the circuit is OK, and the dash lights should then come on.  If you can live with dash lights just being "on" when the lights are on (without having adjustment capability) just bypass this switch.  I did just that on my old VW bug when its dimmer portion of the switch shorted out; then it essentially comes on same as the parking lights coming on.
