Solution

1. Preparation

Gather tools: manifold gauge set, OBD-II scanner, multimeter, basic hand tools.
Ensure the vehicle is parked on a level surface and engine is off. Disconnect the battery for safety.

2. Replace the Cabin Air Filter

Step 1: Locate the cabin air filter access panel (usually behind the glove box).
Step 2: Remove the glove box by detaching the damper and unhooking it from the hinges.
Step 3: Remove the old cabin air filter and clean the housing.
Step 4: Install a new cabin air filter, ensuring it is oriented correctly.

3. Recharge the AC System

Step 1: Connect the manifold gauge set to the low and high-pressure service ports of the AC system.
Step 2: Check the pressure readings to determine if refrigerant is low.
Step 3: If low, connect the refrigerant canister to the low-pressure port and follow instructions to recharge the system gradually.
Step 4: Monitor the pressures while recharging to avoid overfilling.

4. Inspect and Replace the AC Compressor (if necessary)

Step 1: Locate the AC compressor in the engine bay.
Step 2: Disconnect electrical connections and hoses attached to the compressor.
Step 3: Remove mounting bolts using a socket set and remove the compressor.
Step 4: Install the new compressor and reconnect hoses and electrical connections.
Step 5: Evacuate and recharge the AC system after installation.
