Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and screwdrivers.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Remove the Center Console

Use a screwdriver to remove screws securing the center console panel.
Carefully detach the console panel from the dashboard, taking care not to damage any clips.

3. Access the Fan Control Module

Locate the fan control module beneath the center console.
Disconnect the wiring harness from the module by pressing the tabs and pulling it apart.

4. Inspect and Test the Fan Control Module

Visually inspect the module for any burned components or signs of damage.
Use a multimeter to test the module for continuity according to the manufacturer’s specifications.
If the module is faulty, replace it with a new unit.

5. Check and Replace the Fan Motor (if necessary)

If the fan motor was previously tested and found faulty, remove it by unscrewing the mounting screws.
Disconnect the motor’s wiring harness and replace the fan motor with a new one, securing it with screws.

6. Reassemble Components

Reconnect the fan control module and any associated wiring.
Reattach the center console panel, ensuring all clips and screws are securely in place.
Reconnect the negative battery terminal.
