Re: 68 hideaway headlights
"when starting the car the hideaway doors will open all the way then close"
You need vacuum at the control valve to open the lights
You cannot have vacuum to the top of the control valve to open the doors.
The vacuum source for the headlight switch is very close to the reservoir supplying vacuum to the control valve.
When starting the car you, basically have no or very low engine vacuum. Interesting your car will hold vacuum in the headlight system after it has been shut off.
This problem happens while cranking the engine? Or it happens once it is running?
I'm thinking out loud
