Ensure the vehicle is parked on a level surface.
Disconnect the battery for safety.

Tools Required:

OBD-II scanner
Manifold gauge set
Socket set
Screwdrivers
Safety goggles
Gloves

2. Inspect and Repair Leaks

Locate any visible leaks in the AC system.
If leaks are found, use an AC leak sealant or replace the damaged component (e.g., hoses, condenser).
Recharge the AC system with refrigerant as per manufacturer specifications.

3. Check and Replace Cabin Air Filter

Remove the cabin air filter cover, typically located behind the glove compartment.
Take out the old cabin air filter and inspect for dirt and clogs.
Install a new cabin air filter, ensuring it is oriented correctly.

4. Test and Replace AC Compressor (if necessary)

If the compressor is not engaging, check the wiring and fuses associated with the AC system for damage.
If the compressor is faulty, remove the old compressor by disconnecting refrigerant lines and electrical connectors.
Install a new AC compressor, ensuring proper fittings and connections.

5. Recharge the AC System

Connect the manifold gauge set to the high and low pressure ports.
Follow the manufacturer's specifications to recharge the AC system with the correct type and amount of refrigerant.
Monitor the pressure readings to ensure the system is operating within normal ranges.
