My corvette stingray?

[Brad]

Hey i've owned my 1975 corvette stingray for little over a year now, and just about a couple months ago. my headlights wont go down, I've manually taken the springs out and put them down, they go back up fine with the controls in the cab, but wont go down. Any ideas? I think it might be a vaccum leak but not sure since theres dozens of hoses.

Definitely vacuum leaks. I'm betting that before they quit going down, they opened over night and were open every morning.
All of your hoses probably need replaced, so go buy a couple rolls and get started. There should be some check valves, too, but if there isn't, you may want to install one on each door. Spray your new hoses liberally with silicone spray and they will last longer.
