rear daytime running light out
my rear day time running light or fog light are out only on my passenger side tail light the break lights and reverse lights still work i have changed the bulbs twice and they haven't came back on, been looking at the fuse boxes and the diagrams and for some reason GM could not just simply put "rear drl" or like "taillights" they had to put everything is tech language lol so I'm asking today does anyone know which fuse is for my rear tail lights specifically the right one and the daytime running light you know the little red strip that's lit while you cruise at night so people can see you lol.....thank you

Fuse F28 in the engine compartment block (named "Body control module 3") is the only one associated with passenger side rear lighting functionality, try that one.
This fuse controls the side marker lights, too, so if those are lit on the passenger side and only the tailllight segments aren't coming on, then the most likely culprit is unfortunately the taillamp assembly.

Still no passenger side daytime running light so it can’t be one of these fuses also the rear side marker on passenger side is out as well which leads me to believe it is still a bad fuse…but which fuse? Took her to Chevy today they said they won’t have available appointment untill next Friday so forget that I’ll have 2 tickets by then lol. At this point I’m lost because if it was the wiring harness for the rear daytime running bulbs then the side marker would be back on due to change of potentially blown fuse, however both are still out so could it be a bad ground? Someone please help. |

Here are the complete diagrams from the service manual associated with the taillight assemblies (except for the backup and the separate EU/Asia rear fog lamps), this will help you troubleshoot the harnesses and fuses involved.
T4F is the RPO for the uplevel lighting (HID+LED on the SS and LT w/convenience package), T90 is the EU/Asia specific rear lighting option code. A minus symbol before these option codes means the signal path is only present on cars without the option, and no preamble codes denote signal paths on cars with the option.
