Just Replaced Headlight Actuator Seals
And I have lights that pop up and down in a flash. Thank goodness. They used to work fine until one of the guys in my club wanted to look at the squirters and manually operated the drivers side light, that was the last time it came up on its own.
I do however have a question. The passenger side comes up slower and goes down slower. Is there a way to make them operate in unison?
I must have a leak somewhere because as quick as the car is shut down the vaccum goes away. I just replaced all the lines so I know it is not that. It must be the reservior, now that is gonna be fun to get out.
Can you help me with the up and down speeds? Thanks for any help.

Have you checked the vacuum relay? I don't remember which year it changed but I think you only have one... My reseviour doesn't hold vacuum after the car is off due to these being faulty. If you didn't replace your check valve (near the engine) and it is bad, that would also cause a loss of vacuum. A $25 vacuum pump and the vacuum troubleshooter at http://www.corvette-101.com can help you narrow things down for sure, like it did for me :thumbs:

Edit: If this isn't a possible cause for the differing speeds, I'm looking for that answer too!

Well one thing to check is the four springs that actually help the vacuum flip them. On my car, I had two missing and one broke, so I replaced all eight and they are up and down in a snap.
Easy to check, just look up under the front as you can see them on the sides,
hope it helps :seeya

A vacuum pump and test kit will help diagnose your problems. My experienced guess is that the relay is your problem. Unfortunately these are the most expensive of the system, so, invest in the vacuum pump and troubleshoot the cheaper parts first, such as hoses and ensure they're not the problem.
Troubleshooting the system is trial and error. You will learn as you get your hands dirty and the system will begin to make sense and you'll become an expert quickly. It's a quirky little system but with a vacuum pump and one of the online guides, you'll find the problem quickly.
Good Luck.
