Default Pop-up headlight issue

New C5 owner (first Vette) and new to this forum. Purchased a 99 FRC from the original owner with 35K miles on the clock. Pristine maintenance over the years. Both headlights pop up and close perfectly fine when the engine is off, no funny noises or grinding; however, when the car is running, they will only open about 10% of the time. I've seen a lot posted on the lights but nothing exactly like this. If it were the switch, I would think it wouldn't matter if the engine is running or not. Any ideas would be appreciated! Thanks.

Thanks for the quick response and details. I'll give it a look to see if there is any corrosion or if the ground is loose. Appreciate the help!

I followed the schematics and found the ground and splitter pack. Not a drop of corrosion on the screw or inside the plug. The motors work and sound great when the car is not running but once in a while if I turn the light switch very quickly, I can get the lights to pop up when the car is running. Wondering now if there is some sort of short coming back to the stalk?

Default Problem fixed

Sometimes it's the easiest solution. Tightened the battery terminals and the lights function normally. It also solved the flickering radio issue. Thanks for the help.
