2007 Kia Sedona Radiator fans

Actually, the diagnostic fault code did not say to replace a part. They never do. Fault codes only indicate the circuit or system that needs further diagnosis, or the unacceptable operating condition. When a part is referenced in a fault code, it is only the cause of that code about half of the time. You also have to consider grounded or broken wires, stretched or corroded connector terminals, and mechanical problems related to that part.

In this case a typical failure would be a tight fan motor that overheated the control module which shorted and blew a fuse or fuse link wire. That would require replacing three parts. You may have replaced one that was needed, but that's as far as you went.

The people at auto parts stores are not the ones to call for advice. They understand how to find and sell parts, not diagnose and repair problems.

There is a fan relay mounted on the back of the fan assembly, but we can skip past that for now. Go right to the 8-pin plug for the fan control module and unplug it. There should be three black wires. Use an ohm meter to measure their continuity to ground. Two should have continuity;... Maybe a couple of ohms. Once those are identified, the third one should have 12 volts. That may only show up when the engine is running. If you never find that 12 volts, we have to work backward to see where it's getting lost.
