scrappy here i have one headlight that keeps popping up when i turn the car off.
now ive rebuilt both actuators, and replaced the vacuum actuator relays with new units from wilcox corvette parts. they actuators are only about 1 1/2 months old. the headlight worked great for the month and a half till last week when the passenger headlight started popping up when i turned the car off. no vacuum leaks anywhere.
i didn't but the previous owner had. i checked them anyways and found nothing. i called wilcox corvette since the relays were new and they said that its VERY uncommon for relays to go bad and there isn't a warranty anyways

You may need to replace the check-valve. It should be in the vac. line that comes directly off of the engine/intake manifold. If it is not working properly, it can cause this. It looks like a small pie-pan, with two nipples on one side, and one on the other. I can send you some vac. troubleshooting info... A new relay doesn't mean it will work. It could have a small internal leak, and since there is a spring inside of them to move the relay valve to the "open" position with no vacuum, there's a chance that the relay is bad. No warranty on the relays?!?!?

Make sure the vacuum llines are actually and completly on..I had a loose one I chased for some time before I found it under the dash! It was wrapped around the brake pedal..everytime I woud stop the headlights went up..I thought it was a source issue untill I found those little manual valves that opened the wiper door and headlights.. I would not be happy about the warranty issue,,give em a second chance and see what happens..hopefully the right thing is done..
J, dont feel bad I chased a no start issue for a week before I figured out that when I put my interior back in i connected a seat belt connection that was never hooked up before. I even bought a new cable for the battery! Glad your issue is cured. Rodney
