Since your system is functioning when you pull down the manual override "pull-down" switch, I suspect the vacuum hose connections on your headlight switch are reversed. Not uncommon. In fact, this hose connection as shown in the diagram on "corvette-101.com" is incorrect. It is also incorrect as shown in the Assembly Information Manual (AIM) for my '78, and I have read that it is also incorrect in at least one other year's AIM.
For correct vacuum hose connections at the headlight switch, the blue-striped line between the headlight switch and the manual override switch "pull down" switch must be connected to the front (firewall side) port and the non-striped line from the check valve must be connected to the rear port.
Please post an update on whether this fixes you problem.
Good luck!

Jim, I was always afraid I would get off somewhere and they would stop coming up at all. I don't mind it like it is but when I let my girlfriend drive at night she can never get them turned off...lol
