Since they work (kind of) one or both of the headlight actuators might have a vacuum leak. If you have a hand vacuum pump, you can diagnose the actuators by connecting a hose to the vacuum port on the bottom of the headlight actuator (the bottom port opens the headlamps, the top port closes the headlamp) and see if you can pump each headlamp open manually. If you can't open them with vacuum, the actuator shaft seal is probably worn out and leaking. The seal costs about $10 at the Vette parts distributors. A lot cheaper than buying new actuators. Just be carefull disassembling the retainer that holds the seal in place, the tabs that are bent over are fragile. Good luck.
