had a customer come in, wasn't charging. Used shop cord, charged right up on one of the two ports. Port closest to hinge not working for power or data. No biggie, right? Wrong. Replaced the port assembly and still no change to the lack of use on the usb port. Is there a component on the board that could be causing the issue?

Absolutely.
Every port, or input will have components on a circuit board that regulate its function. First thing I would do here is inspect the old USB-C board, if you still have it, as well as the area on the back side of the logic board.
May times there could be damage to the port where pins where bent, or corrosion crossed some lines and did some damage to the USB controller affiliated with that port. You may be able to see physical damage or blown components in this area. It's the flip side of the board from the USB board connector and most of the components here are related to USB function. The two large chips are the controllers for the ports, which also assist in negotiating charge, but I would lean towards something else in this case. A bad chip in this pair can cause the device to not power at all.
