MB958178 Auto Air Conditioning Compressor For Mitsubishi Carisma WXMS010

Your car's air conditioning compressor pumps refrigerant to provide cool, comfortable air to your vehicle. Without refrigerant circulating, your car won't be able to cool the interior, causing the air conditioning system to produce only warm air.

Need To Replace The Situation

Here are some additional symptoms that might indicate a faulty AC compressor requiring replacement:

1. Loud or unusual noises: If you hear grinding, squealing, or rattling noises coming from the AC compressor, it could indicate internal damage or worn-out components.

2. AC system not cooling: If warm air is blowing through the dash vents even when the AC system is turned on, it could mean that the compressor is not functioning properly. This could be due to a lack of refrigerant or internal damage.

3. Excessive vibration: Excessive vibrations while the AC system is running can be a sign of compressor issues. This could be caused by worn-out or damaged compressor components.

4. AC system repeatedly cycles on and off: If your AC system frequently turns on and off rapidly, it could indicate a faulty compressor. This is known as short cycling and could be caused by a refrigerant leak, a malfunctioning pressure switch, or a failing compressor.

5. Burning smell: If you notice a burning smell coming from your AC system, it could indicate that the compressor's motor or wiring is overheating.

6. Oil or refrigerant leaks: Leaking refrigerant or oil around the AC compressor can be a sign of a failing compressor that needs to be replaced.

7. High pressure or low-pressure readings: An experienced technician can diagnose a faulty compressor by measuring the pressure levels in the AC system. If the pressure readings are abnormal, it could be an indication that the compressor is malfunctioning.

If you are experiencing any of these symptoms, it is best to have a professional HVAC technician inspect and diagnose the issue. They will be able to determine if the AC compressor needs replacement or if there are other underlying problems that need to be addressed.

AC compressor replacement process.

1. Drain the refrigerant: Before starting the disassembly, the technician needs to use special equipment to drain the refrigerant from the entire air conditioning system to ensure work safety. This is very important because refrigerants are toxic and harmful to the environment when released into the atmosphere.

2. Remove the drive belt: The technician will remove the drive belt from the AC compressor clutch pulley and separate the clutch from the wires. This makes it easier to remove and replace the compressor.

3. Disconnect the refrigeration lines: The technician will need to disconnect the low-pressure and high-pressure refrigeration lines that are connected to the compressor body. These lines are usually connected by quick connectors that technicians can remove using special tools.

4. Replace the compressor: The technician will unbolt the damaged compressor and remove it. They will then install a new AC compressor and re-tighten it.

5. Reconnect lines and drive belts: Once the new compressor is installed, technicians will reconnect the low-pressure and high-pressure refrigeration lines. They will then reattach the drive belt and wires, making sure everything is connected correctly.

6. Refrigerant charge: After replacing the compressor, the refrigerant in the air conditioning system has been drained, so the technician needs to recharge the refrigerant according to the manufacturer's specifications. This often requires the use of special tools and equipment to ensure proper filling.

7. Verify system operation: Once the refrigerant charge is complete, the technician will test and confirm that the AC system is operating properly. They will check various functions of the air conditioner, such as the amount of air being blown out and the temperature, to make sure everything is working properly.

This is the rough AC compressor replacement process. Remember, before any air conditioning system repair or replacement work is performed, it is best to have it performed by a professional air conditioning technician to ensure the work is done safely and correctly.
