Everyone has answered your switch question.  It either is tucked up there somewhere or has been removed.  It is missing, it shouldn't be a big deal to replace it other than the cramped space for getting the vacuum lines figured out and re-routed.  But if one headlight works, the problem is downstream of the switches.  There was just a good post about troubleshooting them.  We advise replacing the vacuum hoses with a new kit, since they always are getting pretty dry.  That usually solves the problem, and is maintenance that should be performed anyway.  If you still have a problem, check the vacuum relays and actuators.  You can re-route a vacuum line to go directly to each side of each actuator to test if they work.

Have fun

 ok, the headlight that won't come up, won't budge when you try and help it. Coule the vacume lines be crossed?[QUOTE=VetteSpecialties]Everyone has answered your switch question.  It either is tucked up there somewhere or has been removed.  It is missing, it shouldn't be a big deal to replace it other than the cramped space for getting the vacuum lines figured out and re-routed.  But if one headlight works, the problem is downstream of the switches.  There was just a good post about troubleshooting them.  We advise replacing the vacuum hoses with a new kit, since they always are getting pretty dry.  That usually solves the problem, and is maintenance that should be performed anyway.  If you still have a problem, check the vacuum relays and actuators.  You can re-route a vacuum line to go directly to each side of each actuator to test if they work.

[QUOTE=zgator][QUOTE=maintenance4]Remove the  screws holding the cover under the column and you will see the vaccum switch. Two small screws hold the switch to the cover. Hope this helps...[/QUOTE] Are you talking about the overide or something else? If it is what do I do with the vacume switch?[/QUOTE] The reason you can't find the vaccum switch is because the pull-down stem is probably broken off as was mine. Replace the switch and get yourself a vaccum diagram to trace back to your headlights...

Michael, I set ya some headlight troubleshooting info(MS Word doc) via e-mail. Hope it helps.

Hi Adam!

Done

Got it!

Thanks Adam!!! Got it!!

I think the overide switch under the dash is just a release vacuum switch  for headlights. I can't say that I knew there was an overide switch for the tail lights, I learn something every day. Gene

[/QUOTE] No it was a two part question. You are right about the overide switch. The tailight ? was about the smoke colored lenses that covered my rear lights. They weren't screwed in and I wasn't sure how they came off. I figured it out and ripped them out. I don't like them and have never bought any so I didn't know how they were installed, they were so dark that I couldn't see behind them so I had my wife turn on the lights and that only made matters worse. All I got was glare.
