Solution

1. Preparation

• Gather tools and parts required for the repair.
• Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Remove the Cabin Air Filter

• Locate the cabin air filter access panel, typically found behind the glove compartment.
• Open the glove compartment and remove any screws or clips holding the access panel.
• Carefully pull out the old cabin air filter and check for debris or blockages.

3. Inspect and Replace Blend Door Actuator

• Reinstall the new actuator, ensuring it is properly aligned and securely fastened.

4. Check and Replace the Blower Motor

• Disconnect the blower motor wiring harness.
• Remove the screws or clips securing the blower motor to its housing.
• Inspect the blower motor for obstructions and test the motor using a multimeter to check for functionality.
• If faulty, replace with a new blower motor, ensuring it is securely mounted.

5. Reassemble and Test
