Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent any electrical hazards.

2. Replace Cabin Air Filter

Tools Required: Screwdriver, replacement cabin air filter
Remove the glove compartment by unscrewing the screws and gently detaching it.
Locate the cabin air filter housing and release any clips or covers.
Remove the old filter and install the new filter, ensuring correct orientation.
Reassemble the glove compartment and secure it with screws.

3. Inspect and Replace Blower Motor (if necessary)

Tools Required: Socket set, multimeter, replacement blower motor
Remove any panels obstructing access to the blower motor.
Disconnect the electrical connector from the blower motor.
Use a multimeter to test for voltage at the connector when the AC is on.
If no voltage is detected, check the AC control module.
If the blower motor is faulty, remove the securing screws and replace it with a new unit.

4. Recharge AC System

Tools Required: AC refrigerant gauge set, refrigerant
Connect the AC gauge set to the low and high-pressure service ports.
Start the engine and turn the AC to the maximum setting.
Check the pressure readings and determine if the refrigerant level is low.
If low, add the appropriate refrigerant until optimal pressure is reached.
Disconnect the gauge set and ensure all caps are securely replaced.
