Tools required: Socket set, trim removal tools, multimeter, OBD-II scanner.

2. Replace Blown Fuses

Locate the fuse box and identify the specific fuse for the climate control system.
Remove the blown fuse using a fuse puller.
Replace it with a new fuse of the same amperage.
Reconnect the battery and test the climate control system.

3. Replace Cabin Air Filter

Remove the glove compartment to access the cabin air filter housing.
Unclip the filter housing cover and remove the old filter.
Insert a new cabin air filter ensuring proper orientation.
Reassemble the glove compartment and test the climate control system.

4. Repair or Replace Climate Control Module

If the climate control module is diagnosed as faulty, remove it from the dashboard.
Unplug the electrical connectors and remove any mounting screws.
Install the new module by reversing the removal process.
Reconnect the battery and test the system.

5. Recharge Refrigerant (if needed)

Connect a refrigerant gauge to the service ports of the AC system.
