Re: rr brake & turn signal dont work
On my 2017 express 3500. It bcm-6, which is fuse location 72.
Re: rr brake & turn signal dont work
this should be what the underhood fuse box should be like
Re: rr brake & turn signal dont work
None of my rear lights work ( brake, tail , signals, and reverse lights ) I checked all fuses and there fine . Where do I go from here?
Re: rr brake & turn signal dont work
If none of the rear lights work (brake, turn and reverse) and all the fuses are good, I would look at the wire harness connection. there should be a connector the goes to all the rear lights in the wire harness. See if it has been cut or unplugged.
Re: driver tail light out and no trailer running lights
So some guys hooked a trailer up to my Chevy 2500 express 2016 model. Since then my driver tail light doesn’t work nor does my trailer running lights. All fuse are good, even took to another shop today and they said they couldn’t figure it out. Any suggestions would be great.
Re: rr brake & turn signal dont work
the tail light fuses are under the drivers seat. LT REAR PARK LAMP FUSE. RT REAR PRK LAMP FUSE. Thay both get power to the fuses from the park lamps relay. If you have power on both fuses but one tail light doesn't come on you have a bad connection the the light that is out or you have a bad/wrong bulb in the tail light. Is the license plate light working? Brown wire is for tail lights. Both sides and license.
I would completely remove the trailer wiring first and then see how everything works. Probably could be a bad wiring job.

Hey I got a 2019 gmc savana 2500. Both my signals flash rapidly but all my signals headlights etc are fine, could This model have a relay that’s wired to the signals that’s bad or is it all controlled by the bcm? All lights are replaced & are oem and I bought the car like this. Hoping it’s not to do with a bad ground.
Re: rr brake & turn signal dont work
there's no flasher for the turn signal. They use the BCM to pulse the turn signal. As long as everything works, I would just let it flash fast.
The bulbs for your vehicle should be 3157. It is possible that someone replaced them with 3057. I don't know if that would cause the fast flash though. They are slightly different in lighting and power usage but I don't know if that would affect the flash time.
