05 Chevy 2500 no tear running lights

[Waystro]

So just bought a 05 Chevy 2500 6.0 gas the drivers side running lights works. But the passenger side has no running lights but blinker and brake lights work. I’ve checked all fuses all good except for the veh chmsl was blown changed it no change also replaced the bulb still not working. Any ideas?

Did you check the socket for power and ground?

I have not I don’t have a volt meter. I do have a check engine light but don’t know if it’s related. The ground at the back of truck bolted to frame is super dirty/rusted but I would think if the ground was bad then the blinkers wouldn’t work right?

I wouldn't be so sure. Electrical can do some real weird things. Especially in the case of bad grounds. Lol

How about are any of the bulbs led bulbs? If one has been replaced in line of those ones and it was installed the wrong way it will not flow current through it possibly causing this?

There all regular bulbs
Maybe the junction box on frame is bad? Or harness to that side is?
Now I can live with no running light but if I turn on the headlights shouldn’t it light up since DRL lights on on?
Don’t really want to get pulled over even though my brake(when I press pedal) works and blinker. It’s my bosses old work truck that is son has been driving a year with no running light and 2 year old tags

I've read that Left and Right are on different fuses.
Also I read about a fuse box on the passenger side, in a area below the airbag. Can't say specifically what year that was though.
One guy had a bad headlight switch, but that was no running lights at all.

Are there separate relays for each side? Our 2003 6.0 has a bad relay on one side with similar issues, food for thought

Wes was it the relay under the hood?

Yessir, connection was pretty dirty as well but after cleaning it up and replacing relay all was well again.

Awesome I’ll pick one up tomorrow and see if that fixes it fingers crossed
