Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, Phillips screwdriver, flathead screwdriver, and replacement cabin air filter (if necessary).
Ensure the vehicle is parked on a level surface with the ignition off.

2. Check the Blower Motor Fuse

Locate the fuse box (usually under the dashboard on the driver's side).
Remove the cover and locate the blower motor fuse.
Inspect the fuse for continuity; replace if blown.

3. Inspect and Replace Cabin Air Filter

Open the glove compartment and remove any contents.
Release the stops on the sides of the glove compartment to allow it to drop down.
Locate the cabin air filter cover and remove it.
Take out the old filter, inspecting it for dirt and debris.
Insert a new filter, ensuring it is oriented correctly, and reattach the cover.

4. Test the Blower Motor

Disconnect the blower motor connector.
Use a multimeter to check for voltage at the connector with the ignition and HVAC system on.
If voltage is present, the blower motor may need replacement; if not, investigate wiring back to the HVAC control module.

5. Inspect HVAC Control Module and Wiring

Remove the dashboard trim if necessary to access the HVAC control module.
Check for any visible damage to the wiring harness and connectors.
Repair or replace any damaged components as needed.

6. Reassemble and Test

Reinstall any components removed during the process.
Start the vehicle and test the HVAC system for proper airflow.
