just installed all new components for 1968 vacuum headlight system and when i turn on the lights and the actuators move slightly. I force them open and then when i turn off the lights the light covers close very slowly. I'd like to know if im dealing with a vacuum problem or is there something else going on?

These covers do not open and close super fast. I take it they try to open but do not.

What diagram did you use to connect your hoses?

Do you have a vacuum leak?

How much vacuum are you pulling?

Is the underhood switch working properly, and is there any binding when you open them manually?

Just some things to check and if you haven't seen it already we have a diagram in the tech section here https://camaros.net/techref/articles/ftecref001.html.

I'd be interested in knowing your vacuum as well. Is your motor stock? If it's cammed up, you may not have enough vacuum for them to work properly.
