Can anyone tell me which fuse this USB port is on a 2019 Tahoe? I have tried to narrow it down but cannot find it. The USB port on the right works but the one on the left that I am point to does not and I just want to know which one it is.

If you share your vin or some more info like vehicle trim and details I can help you out, but this is not specific enough atm.

Helps but still not enough, the diagrams are very specific based on the RPO codes. want to share your vin or snap a picture of the SPID tag with the QR code?

Thank you, first here is some information from GM on the operation of the USB ports:


The USB port and the card reader slot interface with a hub device, internal to the auxiliary jack, USB, and memory card receptacle assembly. The auxiliary jack, USB, and memory card receptacle assembly receives fused battery voltage and ground from the harness to power the internal hub device as well as providing additional amperage to power USB devices.

The internal hub device interfaces directly with the human machine interface module via a standard USB cable. A Mini type USB connector is used to connect the cable at the USB port and at the human machine interface module and at the auxiliary jack, USB, and memory card receptacle. Standard USB male to female connections are typically used for connecting USB cables together where an in-line connection is required. An in-line cable connection is typically found between the console and I/P harness.

Thanks again for the info it was helpful, as you can see there is a fuse for this system however, both usb ports run off of it. So I don't believe the fuse is the problem.
