Solution

1. Preparation

Gather tools: OBD-II scanner, refrigerant gauge, multimeter, socket set, and safety goggles.
Park the vehicle in a well-ventilated area and turn off the engine.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Recharge Refrigerant

Tools Required: Refrigerant gauge, refrigerant canister (R-134a).
Connect the refrigerant gauge to the low-pressure service port.
Read the pressure level; if low, proceed to recharge.
Follow the instructions on the refrigerant canister to add refrigerant until the correct pressure is achieved.

3. Inspect and Replace the AC Compressor

Tools Required: Socket set, torque wrench.
Remove the drive belt by loosening the tensioner pulley.
Disconnect the electrical connector from the AC compressor.
Unbolt and remove the compressor from its mount.
Install the new compressor, ensuring proper alignment and torque specifications are met (typically 15-20 ft-lbs).
Reconnect the electrical connector and reattach the drive belt.

4. Replace the Cabin Air Filter

Tools Required: None specifically, but may require a flathead screwdriver.
Locate the cabin air filter access panel (typically under the dashboard or behind the glove compartment).
Remove the panel and take out the old filter.
Insert a new filter, ensuring it is oriented correctly (check airflow direction).
Reattach the access panel securely.

5. Check Electrical Components

Tools Required: Multimeter.
Inspect the fuses associated with the AC system (typically located in the engine bay and cabin fuse boxes).
Use a multimeter to check for continuity in the relays.
Replace any blown fuses or defective relays with new ones.
