Headlight system
Hi guys...
Does anyone know where to find information on the headlight systems in a 79' Vette?? I can't find anything, even the repair manual doesn't cover it. Any help would be appreciated...
They don't move, and a lot of the vaccum hoses in the engine compartment have been messed with it looks like. I guess I need a diagram of the routing, and anything else that would help.
Thanks,
Jerry

Hi Jerry,
I don't know if this will help much, but I've attached a scan from my '82 GM shop manual. It's a little hard to read, but I hope it helps a bit.
Good luck.

Re: Headlight system (twotone82)
Thanks, that does help me; now I can attempt to put all the hoses in the right places, and go from there. I wish mine were color coded though... lol.
Are there any components of the system that commonly go bad on these?
Thanks,
Jerry

Re: Headlight system (jerryjfunk)
Jerry,
Just a thought. If your headlights don't move, check your T connectors from the vacuum relays. I had a "lazy" driver's side light (it tended to go up when the lights weren't on or it wouldn't close.) My problem was a crack in the T connector. They tend to dry-up and crack over the years. I couldn't see a crack in it, but as soon as I replaced it, my headlight(s) were fine. 2 bucks for a set of 4 from NAPA.
Also, check the actuator seal(s) (Witches' Hat).

If you want the headlights to go up and down after you install the hoses, better get one of these diagrams.

Re: Headlight system (jerryjfunk)
I believe I found everything I needed on CorvetteFaq.com. There is an entire section on headlight vacuum system repair, along with vacuum hose diagrams.
I hope this helps.
