Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the vehicle's battery to ensure safety during the repair process.

2. Recharge Refrigerant

Tools Required: Manifold gauge set, refrigerant canister.
Connect the low-pressure side of the manifold gauge to the AC service port.
Check the current refrigerant level and add refrigerant as needed to reach the manufacturer's specified level.
Monitor the gauge while adding refrigerant to avoid overcharging.

3. Inspect and Replace Cabin Air Filter

Tools Required: Screwdriver or trim removal tool.
Locate the cabin air filter housing, usually behind the glove compartment.
Remove the glove compartment to access the filter.
Take out the old cabin air filter and inspect for debris.
Install a new cabin air filter, ensuring it is oriented correctly.

4. Check and Replace AC Compressor (if necessary)

Tools Required: Socket set, torque wrench.
Locate the AC compressor and visually inspect for any signs of damage or leaks.
If replacement is necessary, disconnect the electrical connector and remove the mounting bolts.
Install the new compressor, torque the bolts to the manufacturer's specifications, and reconnect the electrical connector.

5. Clean or Replace Condenser and Evaporator

Tools Required: Cleaning solution, soft brush, or compressed air.
Inspect the condenser for debris; if dirty, clean it using a soft brush or spray with compressed air.
For the evaporator, access it through the HVAC housing, and clean as necessary to ensure optimal airflow.
