Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, trim removal tools.
Safety Warnings: Disconnect the vehicle battery before working on electrical components to prevent shorts.

2. Replace Faulty Fuse

Locate the fuse box and identify the climate control fuse.
Remove the faulty fuse using a fuse puller or pliers.
Replace it with a new fuse of the same amperage.

3. Repair or Replace Climate Control Module

Remove the dashboard trim to access the climate control unit.
Disconnect the wiring harness from the module.
If testing indicates a fault, replace the climate control module with a new one.
Reconnect the wiring harness and reassemble the dashboard trim.
