Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, trim removal tools.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Check and Replace Fuses

Locate the fuse panel under the dashboard on the driver's side.
Identify the fuse associated with the climate control system using the fuse box diagram.
Remove the fuse using a fuse puller or pliers and inspect it for damage.
If the fuse is blown, replace it with a new fuse of the same amperage.

3. Inspect Wiring and Connectors

Remove the trim panel surrounding the climate control unit using trim removal tools.
Carefully pull out the climate control unit from the dashboard.
Inspect the wiring harness and connectors for any signs of corrosion, looseness, or damage.
Reconnect any loose connectors securely.

4. Reset the Climate Control Module

With the climate control unit still accessible, perform a reset by disconnecting the climate control module from the harness.
Wait for about 10 minutes then reconnect it.
Reassemble the unit and trim panel.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check if the climate control buttons are responding properly.
Test all functions, including temperature adjustments and fan speeds.
