Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface, and the engine is off.
Safety gloves and eyewear should be worn throughout the process.

2. Check and Recharge Refrigerant

Tools Required: Manifold gauge set, refrigerant.
Connect the low-side gauge to the service port on the AC system.
Read the pressure; if it is low, proceed to recharge the refrigerant.
Follow the instructions on the refrigerant can, connecting the can to the manifold gauge and opening the low-side valve.
Fill until the pressure reaches the manufacturer's specified range (typically 30-40 psi).

3. Inspect and Replace AC Compressor

Tools Required: Socket set, torque wrench, serpentine belt tool.
Disconnect the battery to ensure safety.
Remove the serpentine belt from the AC compressor.
Disconnect electrical connectors and refrigerant lines from the compressor.
Remove bolts securing the compressor and take it out of the engine bay.
Install the new compressor, securing it with bolts and reconnecting the refrigerant lines.
Reconnect the battery and the serpentine belt.

4. Check and Replace Cabin Air Filter

Tools Required: None.
Locate the cabin air filter access panel (usually under the glove box).
Open the panel and remove the old filter.
Install a new cabin air filter, ensuring it is oriented correctly for airflow.
