I need a little help with a head light problem. I was driving my '75 the other night and I put the thing away after that and the drivers side head light would not go back down. The other side works just fine. I don't know much about these systems but I gave the stuff a good visual and didn't see anything that looked funny like a hose off, etc. Could somebody out there give me a good place to start with troubleshooting this thing. Thanks, Darrell

Either the actuator has sprung a leak, or there is an issue with the vacuum relay valve for that side. Most likely the relay valve. Take the hoses off of the actuator(the large "can"), and swap them. If the light goes down then, your problem is with the relay valve. If it does not go down, there is a leak, or other problem with the actuator. The front seals on them go out all the time, but they are fairly easy to replace. IF the relay valve is the problem, you'll need to replace it...no repair for those, but there are a couple of guys that do rebuild them.
