Since the passenger side turn signal and brake light wire of your 2018 Chevrolet Silverado 1500's trailer connector is not having power, then I recommend checking that fuse 17 in your engine bay fuse box is installed and is not blown. This is the fuse that powers your passenger side trailer brake light and turn signal.

You can use a circuit tester like # PTW2993 to test each side of the fuse to see if power is making it through the fuse.

I included a link to a helpful article on trailer wiring for you to take a look at as well.

I have a 2018 Silverado 1500. Since a new rear bumper was installed they said they had to wire an extension to my trailering harness so it would reach the point on the bumper where it attaches. Since then, I have no reverse light on the drivers side, and the trailer running lights don’t work, but they used to before the bumper was installed. Is there a fuse or relay I need to replace? I’ve already changed the bulb on the trucks reverse light but still no power to it.

@Doug For starters, trace that trailer harness toward the front of the vehicle. Is there a plastic clip holding it to the frame? If you can pry that clip out of the frame, you can usually get a few more inches of slack in that harness so you can possibly eliminate that extension harness (which sounds like it's the cause of your problem). If you can't get sufficient slack, unplug that extension and examine the sockets and pins on each side of the connection. Make sure nothing's bent. Plug the harness back in, and make sure it's fully engaged. You might have to push the connection together really hard to get it fully seated. Hopefully, this will get your reverse lamp on the one side of the truck working correctly. As for the trailer taillights, that fuse is located in the engine compartment fuse box in position # 15. Hope that helps!

This sounds like a ground problem on the left side. With the brake lights there is a constant signal coming through which is enough to make the lights illuminate on both sides like they should. But the on/off of a turn signal does not offer enough…
