70 Charger headlight door trouble

Today I installed a new set of LED headlights in my 70 charger R/T, all of the lights fit and worked as they should. The problem is that when I go to shut the lights off when it’s in the low beam setting, the headlight doors won’t close upon shutting off. When the lights are on high beams, the...

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.

I would start at the switch since that is where the changes are made.

1970 has an electric motor, not vacuum-operated. A big improvement IMO.

Can I ask a stupid question? Don't the vacuum operated headlight doors stay closed (via vacuum) when the car is off OR the headlights are off (like the '70 Superbird)?

On the Superbird, the vacuum reservoir stores vacuum when the car is off, to keep the doors closed. Poorly stored vacuum due to leakage (the reservoir, vac lines or the switch), is why you'll see one or both headlight doors creeping open. With weak or no vacuum, springs pop the headlight doors fully opened, as a safety feature.

I'm just wondering if it's the same type system.

doors stay closed only open when light are turned on.
