Hello guys my charger headlight doors stay open i close them manually but as soon as i start the car and they get vacuum they open up & stay up don't matter what position the head light switch is in.I'm thinking a bad vacuum selector on the headlight switch maybe

Check the lines at the switch. One should have manifold vacuum. Make sure there is vacuum first. Then with a hand held vacuum pump apply vacuum to each line one at a time. One will close and the other will open. If all those tests check out than it could be the switch. You need to verify the switch is working off the headlight rocker switch.
 
It's a 1969 charger the vacuum hoses are all new & i think it's holding vacuum as the doors open & stay open as soon as i crank the car over .I'm guessing the switch but was hoping someone has had same issue as it saves a whole lot of work pulling out the switch.As it could also be the hoses are wrong considering it's a repop vacuum like kit

Get the FSM and read page 23-34 explains the system of operation. Its not rocket science.
 
I had the same kind of problem before somebody stole all my vacuum parts from my headlights. I went with the electric conversion kit.
