The eyelids won't go down on my '69 if the headlights are on and I turn off the engine. They will go down and stay down if I first turn the lights off. I replaced the headlight switch. Could it be the valve near the firewall?

Yeah, that check valve is often a problem child. I think Don (WCCC) had some suitable substitutes in stock (from a vette I think)
