'72 headlights/wiper door open at start
Tested everything under the hood as specified
and installed new vacuum lines under the hood.
Did not pull the dash. I checked the line that goes through the dash for holding a vacuum and then spliced in the newly installed lines.
With the car running, everything works correctly.
The only wierdness is that the headlights and the wiper door pop open for a few moments at start up. Once the engine idles a bit, they'll close down and remain closed.
I'm at a loss as to what might be causing this - any ideas?

Look at the check valve.
