I have a 68 Eldo that the headlight doors do not work. I know I'm probably the only one with this problem. I can get mine to open and close by playing with the vacume lines under the hood but I can not get the switch to open them. I would think the pneumatic part of the switch would be failsafe. It looks like the hoses are hooked up correctly to the switch and I do not hear any air leaks under the dash. Is there a common problem to check for?
Other than buying an impossible to find, expensive, new switch is there any other options out there? How about a remote underhood pneumatic switch from another vehicle?
Hoping someone has some experience with this.

Hi ,
Did you ever get the switch to work or finda replacement? JUst curious, I have a 68 and everything except the cruise works.
good luck
