Solution

1. Preparation

Gather tools and parts needed.
Disconnect the battery to ensure safety while working on electrical components.
Tools Required: Socket set, multimeter, OBD-II scanner, flat screwdriver, and pliers.

2. Inspect and Replace the Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the fuse related to the climate control system using the diagram.
Remove the fuse and inspect it for continuity using a multimeter.
If blown, replace it with a new fuse of the same amperage.

3. Repair or Replace the Blower Motor

Remove the blower motor from its housing by unscrewing the retaining screws.
Inspect the motor for any damage or obstruction.
If defective, replace the blower motor with a new one, ensuring proper alignment.
Reconnect all electrical connectors securely.

4. Recharge the AC System (if applicable)

Connect a refrigerant gauge set to the AC service ports.
Check the pressure readings to determine if the system is low on refrigerant.
If low, follow the manufacturer's guidelines to recharge the system with the appropriate refrigerant type.

5. Reconnect Battery and Test

Reconnect the battery.
Start the vehicle and test the climate control to ensure it’s functioning properly.
