Hi Charles,
The headlights can be a bit of a puzzle.
Have you tried to open it by hand to see if the door mechanism itself is operating?
It's best to disconnect both hoses from the actuator when you do this so you don't put any stress on the diaphragm in the actuator.
This test will tell you if you have a mechanical or vacuum problem.
Regards,
Alan

If you changed all the hoses and both relays then the problem might be the seal in the actuators.
Here's a "How to test":

Heres what the parts look like, a lot of the time the center part is bad.

Lubricate all the linkage, it may of just been in enough of a bind that the vacuum could not overcome the resistance. When you manually opened it you may of freed it a bit. Could happen again.
