You can use an R134a recharge kit to recharge your system if the A/C compressor is not working. Typically older cars may have very slow leaks that may require top-off with refrigerant every couple of years. One other reason why the A/C compressor does not engage is the fact that the system may be low on R134 refrigerant. If that unit detects an error it will not engage the A/C compressor to avoid it getting damaged. Remember that the A/C clutch is controlled by the A/C Control Unit. If it doesn’t do not assume that the A/C compressor itself is the problem. When the A/C system does not blow cold air the first thing that you show check is if the compressor engages. Why your air conditioner clutch doesn’t engage? The following video explains how the clutchless variable displacement A/C compressors work. You will not be able to check the operation of the A/C compressor clutch on such compressors because there isn’t one. A clutchless variable displacement A/C compressor can be found on models such as W203 C-CLass and W211 E-Class. Mercedes-Benz has started using clutchless variable displacement A/C compressors on many late models. Clutch-Less Variable Displacement AC Compressor The serpentine belt rides the A/C compressor pulley every time the engine runs, but the A/C compressor is working only when the A/C clutch engages it. Once you turn on the AC in the center part of the compressor, the AC clutch should engage and start to rotate with the pulley. The center part on the pulley of the A/C compressor will not spin when you have the air conditioner off or if there is a problem. The center part (the clutch) should be engaged and should be spinning along with the pulley. Now, look at the pulley of the air conditioner compressor.Open the hood and look at the serpentine belt to locate the AC compressor.How to tell if your air conditioner AC compressor clutch is working/engaging? This video is helpful if you are trying to troubleshoot air conditioner problems, the A/C compressor clutch in particular. Test if the A/C compressor clutch is engaging If there are error codes on the A/C Control Unit the compressor will not engage and you will need to reset the fault codes using a diagnostic scanner such as the YOUCANIC full system scanner. The A/C compressor clutch engages to create high pressure in the refrigerant and its state is controlled by the Air Conditioner Control Unit. By compressing the refrigerant we add pressure to the system. Otherwise, the A/C compressor engages and starts to compress the refrigerant. If no problems are detected such as low refrigerant in the system, it sends a signal to disengage the A/C compressor clutch. When you turn on the A/C, the clutch engages and the pistons start to compress the refrigerant. The Air Conditioner control unit starts gathering input from an array of sensors on your Mercedes-Benz. Every time you want cold air to blow on your Mercedes-Benz cabin you turn on the climate control and set your desired temperature. While the A/C compressor on your Mercedes-Benz is an important part of the system, the A/C compressor clutch is even more important. It is important to understand how to check if the A/C compressor is engaging or not. One crucial element of the A/C compressor is the clutch. The A/C compressor is the heart of the system.
