Hey, i am new to the group, i have owned many of chevys in the past, but this kinda has me stump. Just installed new tail lights wiring harness (old one was all cut to hell by perious owner with LED lights), So i went and got new light wiring and for some weird reason, i have running lights on driver side just fine with blinker brake backup and running light, now how ever on the passenger side, i just have brake blinkers and backup, no running lights on my back or front passenger side now? I have replaced all the bulbs as i changed out the wiring. I have checked all the fuses, and the connectors. just at a stand hold now.

Check the grounds, but without being able to fully inspect the damage to the wiring first hand, it’ll be really hard to say. The only suggestion would be to get a wiring diagram and start wire tracing/testing, inch by inch. But, if you have 12v voltage to the socket, I’d say it’s a ground.

 

Did you ever get this problem figured out? Having the same issue. Had the lights replaced and no change. Fuse was checked and changed.
Thanks.
