Use a multimeter to test the fuse; if blown, replace it with a new fuse of the same amperage.

3. Climate Control Module Inspection

Remove any trim or panels that obstruct access to the climate control module.
Disconnect the wiring harness from the climate control module.
Inspect the connectors for corrosion, bent pins, or debris, and clean as necessary.
Reconnect the wiring harness securely.

4. Resetting the Climate Control System

Reconnect the negative battery terminal.
Start the vehicle and allow it to run for a few minutes.
Cycle through the climate control settings to see if functionality has returned.
If necessary, perform a hard reset by disconnecting the battery for 10 minutes, then reconnecting.

5. Replace Climate Control Module (if necessary)

If the issue persists, the climate control module may be faulty.
Remove the old module by unscrewing any mounting screws and carefully pulling it out.
Install the new climate control module by reversing the removal steps and ensuring all connections are secure.
