What are the reasons for the Mercedes-Benz C200 air conditioning compressor not working?

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.
When the air conditioning compressor in my Mercedes C200 suddenly stopped working, I started feeling uncomfortably hot. My first thought was whether the AC control switch had failed or if a coolant leak caused abnormal system pressure. Blown fuses in the electrical circuit are also common culprits, so I tried replacing one to see if that would restore function. Issues with the compressor clutch might prevent engagement, and a loose belt could also cause rotation failure. Faulty sensors like temperature probes can make the control module misjudge the situation, leading to compressor shutdown. I recommend regularly monitoring the AC cooling performance - if airflow weakens or strange odors appear, get it checked early. Last time I visited a professional shop for diagnosis, they discovered corroded electrical connectors which worked fine after cleaning. In short, don't attempt deep DIY repairs - prioritize safety and let professionals handle it.
Common reasons for the Mercedes-Benz C200's air conditioning compressor not working include power supply interruptions, such as blown fuses or short circuits in the wiring. Damage to the compressor itself, like internal jamming or poor sealing, is also possible, which is more common in older vehicles. Insufficient refrigerant can trigger the protection switch to stop operation. Control issues, such as faults in the air conditioning computer module, can lead to incorrect signal transmission. For simple troubleshooting, first check the response of the air conditioning button, then inspect the fuse box. If unsure, it's safer to take the car for professional repair rather than attempting random fixes.
