Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to ensure safety while working on electrical components.

2. Replace Cabin Air Filter

Tools Required: Socket set, flathead screwdriver, new cabin air filter.
Remove the glove compartment by unscrewing the screws and gently pushing in the sides to lower it.
Locate the cabin air filter cover and unclip it.
Remove the old cabin air filter and replace it with a new one, ensuring it is oriented correctly.
Reassemble the glove compartment.

3. Inspect and Test Blower Motor

Tools Required: Multimeter, socket set.
Locate the blower motor, usually under the dashboard on the passenger side.
Disconnect the electrical connector from the blower motor.
Use the multimeter to check for voltage at the connector while the blower is activated.
If there is no voltage, check the blower motor resistor and replace if faulty.
If voltage is present but the motor does not operate, replace the blower motor.

4. Clear Ducting Obstructions

Tools Required: Flashlight.
Inspect the ducting visually for any foreign objects or debris.
If any obstructions are found, carefully remove them.
Check for any collapsed or kinked ducting that could restrict airflow.

5. Test HVAC Controls

Tools Required: OBD-II scanner.
Reconnect the battery and start the vehicle.
Use the OBD-II scanner to check for any error codes related to the HVAC system.
Test the HVAC controls for proper operation, including fan speed and temperature settings.
