Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, replacement cabin air filter, and fuses.
Disconnect the battery to ensure safety while working on electrical components.

2. Replace Cabin Air Filter

Locate the cabin air filter access panel, usually found under the glove compartment.
Remove the screws or clips holding the access panel in place.
Take out the old cabin air filter and inspect it for dirt and debris.
Insert the new cabin air filter, ensuring it is oriented correctly.
Reattach the access panel securely.

3. Test Blower Motor

Reconnect the battery.
Use a multimeter to check the voltage at the blower motor connector.
If no voltage is present, trace wiring back to the climate control unit for breaks or damages.
If voltage is present but the motor does not operate, replace the blower motor.

4. Inspect Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the climate control system fuse using the diagram on the fuse box cover.
Remove the fuse and inspect it for continuity; replace if blown.
If the fuse is intact, check for any short circuits in the wiring.

5. Recharge Refrigerant (if applicable)

Locate the low-pressure service port of the AC system.
Connect a refrigerant gauge to check the pressure levels.
If low, follow the manufacturer's guidelines to recharge the system with the appropriate refrigerant type.
