get a probe light tester and check for power at the socket. If you have power at the socket then fix ground issue.
if no power at socket then test backwards towards the power source, Ex. in and out of the switch.
if no power at switch test back to fuses and power supply.
eventually it will lead you to the problem.

Dont have power at the socket. Have power at the dimmer. So headlight swich is good. Bulbs are not burned out. Thare is no fuse. If it was bad ground my sidemarkes would not work either. Thare tide into the same ground as headlights. High beam indicater still works ti so the dimmer is switching the power like its sappose to. The problem is between the light socket and dimmer swich. I haven't bought any parts yet. To poor for that. When it get nicer out above 20F I'll dig deeper. But now it's not worth freezing.
