Default Headlamp Vacuum Help

I recently bought a '78 Corvette (my first). I was installing a new stereo and accidently disconnected both of the vacuum lines on the manual headlamp door switch. The headlamp doors opened. I reconnected both of the vacuum lines but the doors won't close. Does the system have to be reset or something.

That is probably what happened. You'd think that if you cross the vacuum lines that the switch would work just the opposite, but it doesn't.

If that doesn't work, make sure you didn't pull a line loose elsewhere. From the auxillary switch, one line goes up to the headlight switch and the other goes to the vacuum source.

This months Vette mag has a schematic drawing of where all the lines go. I suggest checking it out.
