Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Tools required: Socket set, multimeter, OBD-II scanner, flathead screwdriver, replacement cabin air filter (if needed).

2. Check HVAC Settings

Turn on the vehicle and access the HVAC control settings via the touchscreen.
Ensure the fan speed is set to a usable level and that the system is set to 'Auto' or 'Manual.'

3. Inspect Cabin Air Filter

Locate the cabin air filter compartment, typically found behind the glove box.
Remove the glove box by unscrewing retaining screws and gently pulling it out.
Take out the cabin air filter and inspect it for dirt or blockages.
Replace the filter if it's dirty or clogged.

4. Test the Blower Motor

Locate the blower motor, usually found under the dashboard on the passenger side.
Connect a multimeter to the blower motor connector.
Activate the HVAC system and check for voltage at the connector. If voltage is present but the motor does not run, replace the blower motor.

5. Check Fuses and Wiring

Locate the fuse box and identify the HVAC fuse using the diagram on the cover.
Remove the fuse and check for continuity using a multimeter. Replace if it’s blown.
Inspect the wiring harness that connects to the blower motor for any signs of wear or disconnection and repair as necessary.
