Are all the proper grounds in place? Is your printed circuit board damaged? Is it possible that all the bulbs are burned out? Could there be an issue with your headlight switch? Is your headlight switch turned to the position where the dash light are at their brightest? It may be turned the wrong way causing the lights to be all the way dimmed down. Could it be a blown fuse?

There is a small fuse like 3 or 4 AMPS that will NOT have power on either side (using a test light) till you turn on the lights. After you turn on the lights the fuse will have power and should have power on BOTH sides, if only power on one side, the fuse is blown. If power on both sides the fuse is OK and the switch may be bad. There is a section of the headlight switch that is round, coiled, like a spring, and has been known to break, causing the fuse to blow or just an open circuit. I have also heard of people replacing the H/L switch with the wrong one (looks OK but may have a jumper missing).This also causes no power to the fuse and may have been replaced prior to you owning the vehicle.

Good luck,

Bruce
