Solution

1. Preparation

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

2. Inspect and Replace Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the climate control fuse and remove it using a fuse puller.
Inspect the fuse for any breakage; replace it if necessary with a fuse of the same amperage.

3. Test and Replace Relay

Locate the climate control relay in the fuse box.
Remove the relay and test it with a multimeter for continuity.
If the relay is faulty, replace it with a new one of the same specifications.

4. Check and Replace Blower Motor

Access the blower motor, typically located under the dashboard on the passenger side.
Disconnect the wiring harness and remove the blower motor using a socket set.
Inspect it for damage or blockage; if faulty, replace it with a new blower motor.

5. Inspect Wiring and Connections

Visually inspect the wiring harness connected to the climate control system for any signs of wear, fraying, or corrosion.
Repair or replace any damaged wiring as necessary to ensure proper electrical connections.

6. Replace Cabin Air Filter

Locate the cabin air filter access panel, usually behind the glove compartment.
Remove the filter and inspect for dirt and debris.
Replace with a new cabin air filter to ensure unobstructed airflow.
