68&69 RS's are vacuum actuated and 67s have electric motors. most 68&69 RS parts are interchangeable except the doors and the 69's have a light washer system. the most likely cause of the doors not working on a 68 is a vacuum leak. when i got mine the doors didnt work either. i was able to just cut about a half inch off the end of all the vacuum hoses as they were all dry rotted and split at the ends. RS parts are readily available from most all restoration parts companies.

I think the Vacuum lights were the best bet. I have a 67 RS with the electric motors, although they work, they still suck. and the motors are so expensive... only 1 of mine works correctly now. opens / closes, the other said no way. heheheheh

Yeah, These actuators can be a real pain. Yeah the irst thing I would do is trim an inch off the lines where they connect and check all the lines for leaks. Also, when you either turn em on or off, you sould have a good strong vacuum signal at the actuators. If you don't, It's just like wiring and trace it back to the source. Actuators should have a good bit of resistance when you move the doors back and forth by hand. If they don't, there probably blown. My doors work this week. Ya go to a cruise in and you will always have something to talk about with the "hideaway headlight" guys. It's a good thing rs's look good Have a good one-Dan in WV

One way to check to see if the actuators are OK is to remove both lines on the actuator, plug one line connection (use your finger), and gently try and move the actuator arm. If the arm moves, the diaphram is shot. It is best to do this on the bench. While you have the actuator out, check to see if the hinge assembly is in proper working order. Ditto on the above postings about the hoses. Also check to see if there is a line filter in the vacuum line from the manifold to the vacuum reservior that may be clogged.

You can test the actuators by connecting them to the manifold with a "jumper wire" (peice of hose) if they're good, they'll open. If you car has a lot of cam, you might not get enough vacuam to work the system. All the info you need to diagnose and fix this stuff is out there, but it's still a pain. Went through it on a '69 vette once, got everything to work eventually, except the wiper door always opened by itself when you floored it!
