What are the reasons for the sudden failure of the Mercedes 200L air conditioning to cool?
2 Answers
There are five reasons why the air conditioning of the Mercedes 200L suddenly stops cooling. The following are the factors affecting the sudden failure of the Mercedes 200L air conditioning to cool, the role of air conditioning, and the solutions to the sudden failure of car air conditioning to cool: The reasons for the Mercedes air conditioning not cooling are: Lack of refrigerant; damage to the air conditioning flap; loose drive belt of the car air conditioning compressor; clogged air filter and filter screen; water infiltration into the refrigeration system. Solutions to the sudden failure of car air conditioning to cool: Add refrigerant; replace the air conditioning flap; clean the air filter and filter screen. The role of air conditioning: Filter the air entering the cabin; absorb moisture in the air; keep the air clean and prevent bacterial growth; prevent glass from fogging; adjust the temperature of the cabin.
Speaking of the Mercedes-Benz C200L's sudden loss of air conditioning, I've seen too many cases in my auto repair experience. The most common issue is refrigerant leakage, often caused by aging pipes developing cracks—summer heat increases pressure, making failures more likely. If the compressor fails, the fan stops working; you can check for unusual noises in the engine compartment. Another frequent culprit is a blown fuse—Mercedes vehicles have a fuse box under the glove compartment, often affected by power surges. A loose or broken belt can also disable the fan. Clogged evaporators or dirty filters restrict airflow, reducing cooling efficiency. Don’t underestimate these issues—delaying repairs risks damaging the entire AC system, and driving without AC in summer is dangerous. I recommend visiting an authorized repair shop immediately; Mercedes electronics are complex, and DIY fixes often make things worse. Regular maintenance, like replacing filters and checking refrigerant pressure, can prevent these problems.
