Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and screwdriver.
Disconnect the vehicle's battery to ensure safety during electrical work.

2. Inspect and Replace Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the cover and identify the fuses related to the climate control system (refer to the owner’s manual).
Use a multimeter to test each fuse for continuity.
Replace any blown fuses with new ones of the same amperage rating.

3. Check the Climate Control Module

Remove the climate control module from the dashboard.
Inspect connectors for corrosion or loose wiring.
Clean any corroded contacts with electrical cleaner.
Reconnect and secure the module back in place.

4. Test the Blower Motor

Access the blower motor, usually located behind the glove compartment.
Disconnect the blower motor connector and test the motor with a multimeter to check for voltage.
If no voltage is detected, trace back through the wiring to find the fault.
If the motor is faulty, replace it with a new one.

5. Recharge the Air Conditioning System

Connect a refrigerant gauge to the service ports of the A/C system.
Check the refrigerant levels and add refrigerant if levels are low.
Ensure to use the correct type of refrigerant specified for the vehicle.
