What are the reasons for the Mercedes-Benz C200 air conditioning compressor not working?
2 Answers
Mercedes-Benz C200 air conditioning compressor not working reasons are as follows: Internal wear of the compressor: Severe internal wear of the compressor leads to its inability to function properly. It's important to know that the compressor plays a crucial role in the air conditioning system, primarily responsible for compressing and delivering cold air. This results in the compressor being in a state of high-speed rotation for long periods, which is one of the reasons why the compressor may not work properly. Lack of refrigerant: The car's air conditioning lacks refrigerant. Since the compressor is used to compress and deliver cold air, after understanding this principle, check if there is any leakage in the refrigerant. Without cold air to compress or deliver, the compressor naturally won't work. Circuit system failure: Circuit system failure is a very common reason for the car's air conditioning compressor not working properly. You can check if the circuit is functioning smoothly and inspect the temperature sensor solenoid valve.
When I found that the air conditioning compressor of the Mercedes-Benz C200 was not working, there were usually several main reasons to check. First, electrical issues such as a blown fuse or relay failure might prevent the compressor from receiving the start signal. Second, problems with the refrigeration system, such as refrigerant leakage or the activation of the pressure switch, can automatically shut down the compressor to protect the system when the pressure is too high or too low. Mechanical damage to the compressor itself is also common, such as seized bearings or a loose belt, which can cause it to fail to operate. Faults in the control module may also trigger issues, including errors in the air conditioning control unit or sensor malfunctions. I remember encountering this situation during the last maintenance. It is recommended to first open the hood and check the fuse box. If any abnormalities are found, go to the 4S store immediately to prevent discomfort and safety risks due to air conditioning failure while driving. Regularly inspecting these components during maintenance can help avoid sudden failures.
