Disconnect the battery to ensure safety during electrical work.

2. Inspect and Repair AC System

2.1 Check Refrigerant Levels
- Connect the manifold gauge set to the service ports.
- Read the pressure levels; if low, proceed to recharge the system.
2.2 Recharge Refrigerant
- Use the appropriate refrigerant as specified by the manufacturer.
- Follow the instructions on the refrigerant canister for proper filling.
2.3 Inspect AC Compressor
- Visually inspect the compressor for damage or leaks.
- If the compressor is faulty, remove the serpentine belt and unbolt the compressor.
- Replace with a new or remanufactured compressor and reassemble.

3. Clean or Replace Cabin Air Filter

Locate the cabin air filter housing, typically behind the glove compartment.
Remove the old filter and inspect for dirt and debris.
Install a new cabin air filter, ensuring it is properly seated.
