I would be happy to help.
The trailer light fuses on your 2021 Chevrolet Silverado 1500 Z71 are in the engine bay fuse box and have the following functions:
Fuse 41 is the trailer parking lights
Fuse 54 is the trailer reverse lights
Fuse 73 is the left side trailer stop and turn signal
Fuse 81 is the right side trailer stop and turn signal
Also if needed fuse 63 is the trailer battery circuit.
You can use a circuit tester like # 40376 to test each side of the fuses in question to see if there is power making it through the fuse or not by touching the circuit tester to the small metal tabs on the top of each fuse.
