Default Headlights winking at me

1972 big block, just finished rebuilding vacuum system for lights. All new hoses, override switch, relays and check valve. Didn’t replace dash headlight switch or actuators. When I start the car, the left headlight pops up without pulling the switch. The override switch doesn’t seem to have any affect on the operation of the lights. The right headlight doesn’t go up at all, even if I pull the dash switch. I’m sure all the hoses are plumbed correctly. Any ideas of what is going on will be appreciated. Thx, Bob

When you turn the car off, does that left headlight go back down? I know the default position, an absence of vacuum, for headlights is up... I'm sure you rechecked all your hoses, this is a real puzzle. Any affect on the wiper vacuum system?

Left headlight does NOT go down when the engine is turned off.

Back when I was running the Vacuum system in my 74 I had almost the same issue after replacing everything but the actuators. I finally replaced the actuator seals that are covered up by the dust boot over the rod..when you see them they look like Witches hats! . very easy fix. IMO!! Good luck
