If the USB port in your 2014 Honda Accord is not functioning, there may be a problem with the wiring. In order for the USB port to operate properly, electricity needs to flow from the stereo's head unit to the back of the port. If the wiring becomes damaged anywhere in between, it could prevent the port from working. Damage to the wiring could result from a short circuit, which may cause the wires to overheat and melt the insulation. Additionally, rodents are known to chew on wires, potentially causing damage. A simple way to identify an electrical problem is by using a multimeter to test the contacts inside the port for voltage. It's also important to keep the port clean and free of dirt and debris that could interfere with the electrical connection.
If the USB port in a 2014 Honda Accord isn't functioning, it's important to inspect both the radio fuses and the USB cable connection to troubleshoot the issue.
Consider using electronic cleaner to spray into the port, as it dries rapidly. Additionally, you could also try vacuuming the port to remove any debris present.
