Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working with electrical components.
Allow sufficient time for any heated components to cool.

2. Inspect and Replace Fuses

Locate the fuse box: Refer to the owner's manual for the exact location.
Check the climate control fuse: Remove the fuse and inspect for continuity using a multimeter.
- If blown, replace with a new fuse of the same amperage.

3. Recharge Refrigerant

Connect a refrigerant gauge: Attach the gauge to the low-pressure service port.
Check refrigerant level: If low, use a refrigerant recharge kit.
- Follow the kit instructions to add refrigerant until the proper level is achieved.

4. Replace Cabin Air Filter

Locate the cabin air filter: Typically found behind the glove box.
Remove the glove box: Unclip the stops and lower it down.
Take out the old filter: Pull straight out and inspect for debris.
Install a new filter: Ensure it is oriented correctly as per the airflow direction indicated on the filter.

5. Repair or Replace Blower Motor

Access the blower motor: Remove any necessary panels under the dashboard.
Test the blower motor: Apply direct power from the battery to see if it operates.
- If it does not function, replace the blower motor with a new one.

6. Reassemble and Reconnect Battery

Put back all panels and components removed during the repair.
Reconnect the battery cable and secure it tightly.
