Solution

1. Preparation

Gather necessary tools: fuse puller, multimeter, and owner's manual (for reference).
Ensure the vehicle is parked on a flat surface and the ignition is turned off.

2. Locate the Fuse Box

Open the driver's side door and remove the cover panel under the dashboard to access the interior fuse box.
Locate the engine compartment fuse box, typically found near the battery.

3. Identify and Remove the AC Fuse

Refer to the fuse diagram to identify the AC fuse (often labeled as "AC" or "Air Conditioning").
Use the fuse puller to carefully remove the fuse from its slot.

4. Inspect the Fuse

Visually check the fuse for any physical damage such as a burnt-out filament.
If the fuse appears intact, proceed to use a multimeter to check for continuity:
- Set the multimeter to the continuity setting.
- Connect one probe to each terminal of the fuse.
- A beep or reading indicates the fuse is good; no beep or infinite reading indicates the fuse is blown.

5. Replace the Fuse

If the fuse is damaged, replace it with a new one of the same amperage rating (usually 10A or 15A for AC).
Reinsert the fuse securely back into its slot.

6. Test the AC System

Start the vehicle and turn on the AC to verify that it is functioning properly.
