Solution

1. Preparation

Gather tools: OBD-II scanner, manifold gauge set, multimeter, socket set, and vacuum pump.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical hazards.

2. Recharge Refrigerant

Sub-step 1: Attach the manifold gauge set to the low and high-pressure ports on the AC system.
Sub-step 2: Check the pressure readings; if low, proceed to recharge the system.
Sub-step 3: Use a refrigerant canister and follow the instructions to add refrigerant while the engine runs and AC is set to max.

3. Replace Cabin Air Filter

Sub-step 1: Locate the cabin air filter housing (usually behind the glove box).
Sub-step 2: Remove the glove box to access the filter compartment.
Sub-step 3: Remove the old filter and install a new one, ensuring proper orientation.

4. Repair or Replace AC Compressor

Sub-step 1: If the compressor is damaged, disconnect the electrical connector and remove the mounting bolts.
Sub-step 2: Remove the old AC compressor and install the new one.
Sub-step 3: Reconnect all hoses and electrical connections, ensuring they are secure.

5. Inspect and Clean AC Condenser

Sub-step 1: Locate the AC condenser in front of the radiator.
Sub-step 2: Remove any debris blocking airflow through the condenser.
Sub-step 3: If a leak is detected, replace the condenser as necessary.
