Solution

1. Preparation

Gather necessary tools: fuse puller or needle-nose pliers, multimeter, and replacement fuses.
Ensure the vehicle is turned off and parked on a level surface.

2. Access the Fuse Box

Locate the fuse box as per the owner's manual.
Open the fuse box cover to expose the fuses.

3. Inspect and Test Fuses

Use the fuse puller or needle-nose pliers to carefully remove the fuses associated with the climate control system.
Visually check each fuse for a broken filament or discoloration.
Test each fuse with a multimeter set to continuity mode. Place the probes on each end of the fuse; a beep indicates continuity.

4. Replace Blown Fuses

If a fuse is found to be blown, replace it with a new fuse of the same amperage rating.
Ensure the fuse is securely seated in its slot.

5. Reassemble and Test

Close the fuse box cover.
Start the vehicle and test the climate control system to confirm functionality.
