Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.
Allow the engine to cool before starting work.

2. Check and Replace the Fuse

Locate the fuse box (refer to the owner’s manual for location).
Remove the cover and identify the AC fuse using the diagram.
Inspect the fuse; replace it if it is blown with a fuse of the same amperage.

3. Recharge the AC System

Connect a refrigerant gauge to the low-pressure service port.
Check the refrigerant level; if low, proceed to recharge.
Use the correct type of refrigerant (R-134a or R-1234yf, depending on the model).
Follow the manufacturer’s instructions for recharging the system, ensuring not to overfill.

4. Inspect and Replace the Cabin Air Filter

Open the glove compartment and remove it.
Locate the cabin air filter compartment and remove the old filter.
Inspect the filter for clogs; replace it with a new one per manufacturer specifications.

5. Inspect the AC Compressor

Visually check the AC compressor for any signs of damage or leaks.
If the compressor is not engaging, test the relay and check for electrical issues.
If defective, remove the old compressor and replace it with a new unit, following proper torque specifications for mounting bolts.

6. Reconnect Battery and Test

Reconnect the battery.
Start the vehicle and turn on the AC to test functionality.
Monitor the system for proper operation and check for any abnormal noises.
