2017 GMC Sierra has no reverse lights

[James Crozier]

Hello everyone. I have a 2017 GMC Sierra that has no reverse lights. I replaced the fuse and it blows as soon as the truck is put in reverse. The back up camera works as well as other lights. I am stumped on this one looking for a broken wire. Any help would be greatly appreciated. Thanks

I assume you replaced fuse 33 in the underhood fuse block?  Factory reverse bulbs or have you swapped them for LED ones?

Old post but same problem with my truck wh3n i put in reverse. Fuse 33 always blown after replacing it, tried to change both bulb for led one same issue. Disconnecting rear right harness to try to isolate the problem but samething happen. Any advise anyone ?

You may have to start tracing the wiring towards front of truck. It's possible that there may be some insulation worn off wiring along frame rail and shorting the circuit.

I buy wiring tracer tool to find it but it not shipped yet. Maybe someone got the electric shema for reverse light ? It would certaines help me to find out
