Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, socket set, torque wrench, and a flathead screwdriver.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuses

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Use the fuse puller to check the climate control fuse; replace if blown.
Reconnect the battery after replacing the fuse.

3. Replace Cabin Air Filter

Remove the glove compartment by unscrewing the screws and detaching the stops.
Locate the cabin air filter cover and unclip it.
Remove the old cabin air filter and replace it with a new one (ensure it's oriented correctly).
Reassemble the glove compartment.

4. Test and Replace Blower Motor

Use a multimeter to test the blower motor for continuity.
If defective, disconnect the wiring harness and remove the blower motor using a socket set.
Install the new blower motor and reconnect the wiring harness.

5. Recharge Refrigerant (if necessary)

Connect a refrigerant gauge to the service ports on the AC system.
If refrigerant levels are low, follow the manufacturer's instructions to recharge the system with the correct type of refrigerant.
Monitor the system to ensure proper operation after recharging.

6. Blend Door Operation Check

Remove the panel covering the blend door actuator.
Test the actuator with a multimeter to ensure it is functioning.
If it does not operate, replace the blend door actuator and reassemble the panel.
