Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent electrical shock.

2. Inspect HVAC Fuse

Locate the fuse box, typically under the dashboard or in the engine compartment.
Remove the cover and check the HVAC-related fuses for continuity.
Replace any blown fuses with the same amperage rating.

3. Replace Cabin Air Filter

Access the cabin air filter compartment, usually behind the glove box.
Remove the glove box by detaching the clips or screws.
Pull out the old cabin air filter and inspect it for dirt.
Install a new cabin air filter, ensuring it is oriented correctly.

4. Test and Replace Blower Motor

Reconnect the battery and turn on the vehicle.
Use a multimeter to test the blower motor for voltage while adjusting the fan speed.
If there is no voltage, replace the blower motor.
To replace, disconnect the motor's electrical connector and unscrew it from its mount.

5. Clean Cabin Air Intake

Inspect the cabin air intake located at the base of the windshield.
Remove any leaves, debris, or blockages that may restrict airflow.

6. Verify Climate Control Switch

Test the climate control switch by checking for continuity with a multimeter.
If faulty, remove the switch and replace it with a new one.
