I own a 2020 Silverado Custom. About 2 weeks the turn signal on the passenger side notification popped on the dash. I bought a new turn signal, changed it, and no issues. However, the headlight bulb went out at the same time. Granted both these headlight bulbs were changed about 4 - 6 months ago. I changed the headlight. It works when it is not in the housing. The second I put it inside the housing it does not light up. The brights are not working on the passenger side as well. Have not changed that bulb yet. Curious if there could be another issue. Just want my headlights to work. Thanks for any help that can be given.

 

Two things come to mind. One is that the bulb sockets could be corroded or otherwise damaged. The second is that the ground connection for each lamp is not clean and tight.
