Default C4 headlights

Lot of info on this subject but don't see my particular problem. When I plug in mt headlight harness they close as they should. When I pull the light switch they both come on but only the driver side opens. I have another set of lights so changed the entire gear box and get the same result. I can manually open the lights and leave them like that but it looks so much better when they function properly. Any advice or ideas. 1984 Corvette coupe light and dark bronze.

What happens when you open them manually as you described and then turn them off? Does the one side just stay open??

Open manually both headlights on. Close light switch both headlights close and shut off. Open light switch both headlights turn on, drivers side opens but passenger side remains closed so no one side does not remain open. Thank you for your response.

Try rotating/exchanging the control relays for the light motors. If the problem changes sides then replace the weak relay.

You found the problem, I swapped the relays and the other light worked. Hardest part was finding the relays since my book doesn't even mention them. Thank you so much for your help both of you!!!
