Where is the air conditioning evaporator located in the new Passat?

The air conditioning evaporator in the new Passat is located inside the evaporator box under the dashboard on the passenger side. Automotive air conditioning refrigeration system: The automotive air conditioning refrigeration system consists of components such as the compressor, condenser, receiver-drier, expansion valve, evaporator, and blower. The evaporator is usually hidden inside the evaporator box, making it difficult to spot. Function of the evaporator: The function of the evaporator is to convert high-pressure liquid into gas, which is then blown out by the blower to achieve the cooling effect. Poor air conditioning cooling performance: If the evaporator is dirty, the cooling effect of the car's air conditioning will deteriorate. Therefore, if the air conditioning cooling performance is poor, it is likely due to a dirty evaporator. In such cases, try cleaning the evaporator to see if it resolves the issue. Car air conditioning not cooling: If the car air conditioning is not cooling, it doesn't necessarily mean there's a problem with the air conditioning itself. It could be a normal phenomenon caused by certain objective factors.
Where is the evaporator located? I remember it clearly in the new Passat. It's at the core of the air conditioning system, hidden behind the dashboard. Specifically, it's positioned above or slightly below the glove compartment, where the cold air blows out. The evaporator is the component that allows the refrigerant to evaporate and absorb heat, so when you touch the dashboard area with the AC on, you'll feel a chill. Its location is quite concealed, requiring professional tools for inspection to avoid damaging the wiring or seals. If not cleaned properly, dust buildup can affect cooling performance. It's recommended to regularly maintain the AC system, using cleaning agents to clear the air ducts for a more comfortable and safer driving experience.
I've been driving for years, and the Passat's evaporator is located behind the dashboard. If you bend down from the driver's seat to look, it's connected to the air ducts in the middle-lower position. The evaporator's function is to cool down hot air, and its position is fixed. However, over time, dirt or frost can accumulate here, reducing the air conditioning's cooling efficiency. I think it's best to inspect the evaporator every couple of years to avoid odor or air leakage issues. The location hasn't changed much in the new Passat models, but DIY handling is risky—it's safer to have a professional shop handle the disassembly and installation to prevent damage to the interior. Setting a moderate temperature when using the air conditioner can also help protect the evaporator and extend its lifespan.
