It sounds like the fan motor has gone out which is where I would start by removing the fan to test it by putting power and ground to the motor. I have included how to remove the fan for replacement in the images below.
Here is what is said about the code:
The error code P0480 refers to an issue with the cooling fan control circuit. However, the code you provided, "P0480, " seems to have an additional number, which may not correspond to a specific OBD-II diagnostic trouble code.
Here's some information about the common error code P0480 related to the cooling fan control circuit:
Error Code: P0480 - Cooling Fan 1 Control Circuit Malfunction
Possible Causes:
Faulty cooling fan relay: The cooling fan relay may be defective or malfunctioning, preventing the fan from operating properly.
Blown fuse: A blown fuse in the cooling fan circuit can cause the fan to stop working.
Wiring issues: Damaged or loose wiring connections, shorts, or open circuits in the cooling fan circuit can result in the malfunction.
Faulty cooling fan motor: The cooling fan motor itself may be faulty and require replacement.
Engine control module (ECM) failure: A problem with the ECM could prevent it from properly controlling the cooling fan.
To diagnose and resolve the issue, consider the following steps:
Inspect the cooling fan relay and replace it if necessary.
Check the cooling fan fuse and replace it if it is blown.
Inspect the wiring harness and connections for any damage or loose connections. Repair or replace as needed.
Test the cooling fan motor by applying power directly to it to verify if it operates correctly. Replace the motor if it is faulty.
If all components appear to be in working order, the issue may lie with the engine control module (ECM). Consider seeking professional assistance to diagnose and address any ECM-related problems.
It's worth noting that the specific diagnostic and repair steps may vary depending on the exact make and model of your vehicle.
