Hi, I've replaced the light bulbs, Range Sensor/Neutral Safety Switch, and checked the fuses on my vehicle. Still no reverse lights. I replaced them because the right rear light assembly filled with water due to a crack. Any suggestions?

Good morning,

I see all the parts replaced but see nothing of voltage checks.

I attached a diagram of the reverse lights for you.

Verify the 2 fuses listed have power on both sides. This is not a visual check, it is a voltage check.

There is a relay for this as you can see. It goes through the trailer relay. You need to be sure there is a power to the relay.
