When I turn on the headlights from the instrument panel switch, the low beams go on as expected.
When I click on the high beams from the high beam switch on the floor not only do the high beams NOT go on, the low- beams go OFF too.

I replaced the high beam switch already so I know it's not the switch?

Could it be a grounding issue on the high beam switch?

Anyone have the same issue, or have suggestions on what to check.
Going to try and work on car over the weekend.

TIA
