Solution

1. Preparation

Gather tools and parts.
Disconnect the vehicle's battery to ensure safety while working on electrical systems.
Allow the vehicle to cool down if it has been running recently.

2. Inspect and Replace Fuse

Locate the fuse box, typically under the dashboard or in the engine compartment.
Remove the cover and find the fuse for the cooling fan (refer to the owner's manual for the specific fuse number).
Check the fuse visually or with a multimeter. If blown, replace it with the same amperage rating.

3. Test and Replace Relay

Locate the fan relay in the fuse box.
Remove the relay and test it using a multimeter to check for continuity.
If defective, replace it with a new relay that matches the specifications.

4. Inspect and Replace Fan Motor

Remove the necessary components to access the cooling fan motor.
Disconnect the wiring harness from the fan motor.
Test the motor by applying 12V directly to the terminals; if it does not run, replace the fan motor.
Install the new motor by reversing the removal steps.

5. Reconnect Battery and Test Operation

Reconnect the vehicle's battery once all components have been replaced or repaired.
Start the vehicle and check if the cooling fan operates normally at various temperature settings.
