Get a manual and the test light to check the lighting circuit and see where do don't have voltage. Is there voltage at the fuses?
I have installed 4 new headlights on my 1984 VW Quantum 5cyl. gas, but
> the headlight switch on the dash only lights up the instrument panel
> (dimmer works) and the parking lights. The high beam switch will light

> assembly, to no avail. The fuses 21 & 22 are good. Is there a separate
