Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to avoid electrical shorts.

2. Replace Cabin Air Filter

Locate the cabin air filter housing under the glove compartment.
Remove the cover by unclipping or unscrewing it.
Take out the old cabin air filter and replace it with a new one.
Reattach the cover and ensure it's secure.

3. Inspect and Replace Blower Motor (if necessary)

Access the blower motor, usually found behind the glove compartment.
Disconnect the electrical connector from the blower motor.
Remove the mounting screws holding the blower motor in place.
Replace with a new blower motor if the current one is malfunctioning.
Reconnect the electrical connector and secure the motor.

4. Check and Recharge Refrigerant

Attach refrigerant pressure gauges to the high and low service ports.
Check the pressure readings against manufacturer specifications.
If low, evacuate the system and recharge with the correct type and amount of refrigerant (typically R-134a for this model).
Monitor for any leaks during the recharge process.

5. Inspect Ductwork and Blend Door Actuator

Remove any necessary panels to access the ductwork.
Check for blockages, debris, or damage in the duct system.
Test the blend door actuator by turning the temperature control and ensuring the door moves freely.
Replace the actuator if it is found to be malfunctioning.
