I just purchased a 1976 Corvette. The retractable headlights don't function. It seems to have been disconnected for a while. Can anyone give me suggestion on how to repair this problem?Thanks,Darrell

Take a look at these websites.
You can access diagrams of the headlight vacuum system on them.
Hope this helps.

The best solution, IMHO, is to put in electric motors and do away with the vacuum problems forever. I have them on my 73 and they always work and fast. If yours don't work at all, it may be less expensive to go electric. Send me a PM and I will tell you how to do it.

Like Ben I'm curious about these. Especially if I could make the change fairly cheap.

There is a kit out that allows you to use Firebird electric headlight motors for Sharks. The kit supplies the brackets and such, but you have to source the motors, and electronic control module(s), as well as a later model Corvette headlight switch. There was an article in one of the Corvette rags last year on it...
Check them out here
