Radiator fan issue

The passenger side radiator fan stopped working. I replaced the fan assembly, coolant temp sensor, relays and fuses and still nothing. Im assuming this is a wiring issue at this point. Has this happened to anyone else and if so do you have any recommendations or advice? Thanks ahead of time

Sounds like a wiring issue for sure. Just follow the high fan connector up and find where it runs into the main harness. I want to say it runs into the harness that is along the radiator support but I'd have to look at mine to be sure. Grab a meter and probe the wires on the high side fan connector for 12V too. You can energize both fans by turning on the A/C as it should command both to run so you can check for voltage.

I will definitely try that. Thank you for your help, greatly appreciated!
