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 the engine is off.
Disconnect the battery to ensure safety.

2. Refrigerant Recharge

Step 1: Connect the manifold gauge set to the AC service ports (low and high).
Step 2: Start the engine and turn on the AC to the maximum setting.
Step 3: Check the pressure readings on the gauges. If low, proceed to recharge the system.
Step 4: Add the correct type and amount of refrigerant (R-134a) as specified in the owner's manual.
Step 5: Monitor the pressures while adding refrigerant until they reach the manufacturer's recommended levels.

3. AC Compressor Inspection

Step 1: Locate the AC compressor and inspect the electrical connections.
Step 2: Use a multimeter to check for voltage at the compressor connector while the AC is activated.
Step 3: If no voltage is present, check the AC relay and replace if faulty.
Step 4: If voltage is present but the compressor does not engage, the compressor may need replacement.

4. Cabin Air Filter Replacement

Step 1: Locate the cabin air filter housing, usually found behind the glove compartment.
Step 2: Remove the glove compartment to access the filter.
Step 3: Remove the old cabin air filter and install a new one, ensuring it is oriented correctly.
