Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and the engine is turned off.
Disconnect the negative battery terminal to avoid any electrical issues.

2. Check and Recharge Refrigerant

Tools Required: Manifold gauge set, refrigerant canister, gloves.
Connect the manifold gauge set to the AC service ports.
Check the low and high-pressure readings. If low, proceed to recharge the system.
Follow the refrigerant canister instructions to add refrigerant until the system reaches the recommended level.
Disconnect the manifold gauges and reconnect the service ports securely.

3. Inspect and Replace AC Compressor (if needed)

Tools Required: Socket set, torque wrench, serpentine belt tool.
Remove the serpentine belt by releasing the tension from the tensioner pulley.
Disconnect electrical connectors and refrigerant lines from the AC compressor.
Remove the AC compressor mounting bolts and take out the compressor.
Install the new compressor, ensuring that it is properly seated.
Reconnect refrigerant lines and electrical connectors, and reattach the serpentine belt.

4. Clean or Replace Cabin Air Filter

Tools Required: Screwdriver or trim removal tool.
Locate the cabin air filter compartment (usually under the dashboard or in the engine bay).
Remove the cover and take out the old cabin air filter.
Inspect for dirt and debris, clean the compartment, and install a new filter.
Reattach the cover securely.
