Solution

1. Preparation

Gather all necessary tools and parts.
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 engine compartment).
Use a fuse puller or needle-nose pliers to remove the climate control fuses.
Inspect them for continuity; replace any blown fuses with new ones of the same amperage.

3. Check and Replace Cabin Air Filter

Remove the glove box to access the cabin air filter compartment.
Remove the old cabin air filter and inspect it for dirt and debris.
Insert a new cabin air filter, ensuring it is oriented correctly.

4. Test and Replace Blower Motor

Locate the blower motor, usually found in the dashboard area.
Disconnect the wiring harness from the blower motor.
Use a multimeter to test for voltage at the blower motor connector while the climate control is activated.
If no voltage is present, the climate control module may need replacement; if voltage is present, replace the blower motor.

5. Recharge Refrigerant (if applicable)

Connect a refrigerant gauge set to the AC service ports.
Check the pressure readings against manufacturer specifications.
If low, recharge the system with the appropriate refrigerant, ensuring not to overcharge.
