Why might the headlamp switch now fail to raise the headlamps on a 1977 Corvette?

Rarely is due to switch failure, this system uses vaccum to raise the lights, Trace these lines(very easy) from the vaccum pods near the headlights themselves, back to the source, if no leaks are found, make sure you have vaccum at the intake manifold, if you have vaccum at the manifold then test the switch itself. There is a vacuum cutout switch under the steering colum. it looks like an old style door lock knob, if it in the dowm position the lights will stay up.

Start by reading the manual that came with the car. Check the section on "How to replace headlamps." Might be a good start.

Special order the headlamp online or you might be able to find one on ebay or amazon.

The approximate base price for a Chevrolet Corvette is $54,600. And that is for a new 2013 Chevrolet Corvette. If you were to try an older one then you might be able to find a lower price for one.

You can purchase a 1957 Chevy Corvette different places. There are some car dealers, used or new, that might have them as traded cars, you can check your newspaper, you might find them at car auctions. There is also many Corvette Clubs, you might try to locate one in your area to see if they can help you purchase one.
