Hello everyone. Any electrical experts out there? My trucks headlights do not work, I replaced the bulbs, triple checked the connections several times before reinstalling the lenses, replaced the fuses, replaced the relay, and today I replaced the switch. Everything works, even brights, but no headlights. Any ideas?

 

Hello and welcome.
Is there 12V on your connector when you turn them on?

See if you can find your schematic on gmupfitter.com
