Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's 12V battery to ensure safety while working on electrical components.

2. Access the Blower Motor

Remove the cabin air filter cover by unclipping it (if applicable).
Unscrew and remove the panel beneath the dashboard, if necessary, to gain access to the blower motor.

3. Inspect and Test the Blower Motor

Check the wiring harness connected to the blower motor for any visible damage or corrosion.
Use a multimeter to test the voltage at the blower motor connector while the climate control is activated.
- Expected Voltage: 12V when activated.
If voltage is present but the motor does not operate, the blower motor is likely faulty.

4. Replace the Blower Motor (if necessary)

Disconnect the wiring harness from the blower motor.
Unscrew and remove the blower motor from its housing.
Install the new blower motor by reversing the removal steps.
Reconnect the wiring harness securely.

5. Reassemble and Test

Reattach any panels and the cabin air filter cover.
Reconnect the vehicle’s 12V battery.
Start the vehicle and test the blower motor operation through the climate control system.
