Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a level surface with the engine off.
• Disconnect the battery for safety.

2. Check Refrigerant Level

• Tools Required: Manifold gauge set
• Connect the manifold gauge set to the AC service ports.
• Check the readings on the low and high-pressure gauges.
• If the refrigerant level is low, proceed to the next step.

3. Recharge AC System

• Tools Required: Refrigerant canister and charging hose
• Attach the charging hose to the low-pressure service port.
• Follow the manufacturer's specifications for refrigerant type (usually R-134a).
• Open the valve on the refrigerant canister and monitor the pressure gauge until it reads within the recommended range.

4. Inspect and Replace Cabin Air Filter

• Tools Required: Screwdriver or trim removal tool
• Locate the cabin air filter compartment (usually behind the glove box).
• Remove the cover and take out the old filter.
• Inspect for dirt and blockages; replace with a new filter if necessary.

5. Inspect and Replace AC Compressor

• Tools Required: Socket set, torque wrench
• Locate the AC compressor, typically mounted on the front of the engine.
• Check for any physical damage or leaks.
• If the compressor is faulty, disconnect the electrical connector and refrigerant lines.
• Remove the mounting bolts and take out the compressor.
• Install the new compressor by reversing the removal steps, ensuring proper torque specifications are followed.

6. Reconnect Battery and Test

• Reconnect the battery.
• Start the engine and turn on the AC.
• Monitor the system for operation and check for any unusual sounds or issues.
