Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace Cabin Air Filter

Tools Required: Screwdriver set, replacement cabin air filter
Remove the glove compartment by unscrewing the screws and gently prying it away from the dashboard.
Locate the cabin air filter housing, typically found behind the glove compartment.
Remove the old cabin air filter and check for debris; replace it with a new filter, ensuring proper orientation.

3. Test and Replace the Blower Motor

Tools Required: Multimeter, socket set, replacement blower motor (if necessary)
Locate the blower motor, usually found under the passenger side dashboard.
Disconnect the electrical connector from the blower motor.
Use a multimeter to check for voltage at the connector when the fan is turned on. If no voltage is present, inspect the fuse box for a blown fuse.
If voltage is present but the motor does not operate, remove the blower motor by unscrewing it from its housing and replacing it with a new unit.

4. Inspect Ductwork and Vents

Tools Required: None
Check air intake vents for any blockages, such as leaves or debris, and clear them as necessary.
Inspect the ductwork for any loose connections or visible damage. Reconnect or replace any damaged components.

5. Reassemble and Reconnect Battery

Reattach the glove compartment and secure it with screws.
Reconnect the negative battery terminal.
