Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical shock.

2. Inspect and Replace Blower Motor Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the fuse for the blower motor using a fuse puller.
Inspect the fuse for continuity; replace if it is blown with the same amperage rating.

3. Access Blower Motor

Remove the passenger side lower dashboard cover using a socket set.
Disconnect the wiring harness from the blower motor located under the dashboard.

4. Replace Blower Motor (if necessary)

Remove the mounting screws securing the blower motor using a socket set.
Carefully pull out the blower motor from its housing.
Install the new blower motor in reverse order of removal, ensuring it is seated properly.
Reconnect the wiring harness.

5. Reassemble Dashboard and Test

Reinstall the lower dashboard cover and secure it with screws.
Reconnect the battery.
Start the vehicle and test the blower motor at various speed settings to confirm functionality.
