Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Check and Replace Fuses

Tools Required: Fuse puller or small pliers
Locate the fuse box, typically found under the dashboard or in the engine compartment.
Inspect the fuses related to the climate control system. Replace any blown fuses with new ones of the same amperage rating.

3. Replace Cabin Air Filter

Tools Required: Screwdriver or trim removal tool
Open the glove compartment and remove it by either detaching the stops or unscrewing any screws.
Locate the cabin air filter housing, usually behind the glove compartment.
Remove the old filter and replace it with a new one, ensuring it is oriented correctly for airflow.

4. Inspect and Test Blower Motor

Tools Required: Multimeter, socket set
Access the blower motor, typically located under the dashboard on the passenger side.
Disconnect the electrical connector from the blower motor.
Use a multimeter to check for voltage at the connector when the climate control is activated. If no voltage is present, further investigation into the wiring or control module is needed.
If the motor is faulty, replace it with a new blower motor.

5. Reconnect Battery and Test

Reconnect the vehicle battery.
Power on the vehicle and test the climate control system to ensure proper functionality.
