2005 Tahoe DRL not working

[Rbernardi]

I noticed on my wife's Tahoe that the driver rear drl wasn't working. So I pulled the taillight, socket looked brown/burned, checked the bulb, it was blown, replaced it, boom go to go.

A few day later she's pulling away and the same one is out. I checked it and the bulb was fine this time. So I got a new harness for the rear driver side, and it's still not working. All the other daytime running lights worked except for the driver rear. Any suggestions?

I wasn't aware that drl used rear lighting as well? Thought it was only front lights?

Ya there are a lot of threads on the front DRL, but the rear are on all the time as well.

I dont think thats correct. Never heard of rear drls on any GM vehicle. Rear fog lights, yes..but not drls.

They should not be on all the time. The rears are driving lights that should only be on with headlights.

Ok, I thought the rears were considered running lights. I don't know what would be causing just the driver side to no work, even with a new harness in that corner.
