Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shorts.
Allow the vehicle to cool down before servicing.

2. Check and Replace Fuses

Locate the fuse box (typically under the dashboard or in the engine compartment).
Identify and remove the climate control fuse using a fuse puller.
Inspect the fuse for continuity; replace if blown.
Reinsert the new fuse and reconnect the battery.

3. Replace Cabin Air Filter

Open the glove compartment and remove any contents.
Remove the stops on the sides of the glove compartment to allow it to drop down.
Locate the cabin air filter cover and remove it.
Take out the old cabin air filter and replace it with a new one (ensure correct orientation).
Reassemble the glove compartment.

4. Test Blower Motor

Access the blower motor, usually located under the passenger side dashboard.
Disconnect the electrical connector and test the motor with a multimeter.
If the motor is faulty, remove it by unscrewing the retaining screws and disconnecting any attached ducts.
Replace with a new blower motor and reconnect the electrical connector.

5. Recharge AC System (if necessary)

Attach a refrigerant gauge to the low-pressure service port.
Check the pressure; if low, proceed to recharge the AC system with the appropriate refrigerant type (R-134a or R-1234yf).
Start the engine and turn on the AC to circulate the refrigerant.

6. Inspect and Repair Actuators

Remove the dashboard panel as necessary to access the HVAC control module.
Inspect the actuators for any physical damage or disconnection.
Test the actuators by applying voltage directly to check functionality; replace if defective.
