5Q0201801 Volkswagen evaporativ

The evaporator is really the heart of your car’s air conditioning system. It takes the refrigerant—that’s the stuff that actually gets cold—and it turns it from a high – pressure liquid into a low – pressure gas. That process is what absorbs heat from the air blowing through it. Think of it like a radiator, but instead of getting rid of engine heat, it's pulling heat out of the air in your cabin. It’s where the cool air actually comes from. It sits inside the HVAC system—that’s your heating, ventilation, and air conditioning—usually behind the dashboard. The blower motor forces air across the evaporator’s fins, and that’s what you feel coming out of your vents. The evaporator is connected to other parts, like the expansion valve and the condenser, to create a closed loop where the refrigerant cycles. It's a key piece. Well, if this part fails, you won't get cold air. At first, you might notice reduced airflow, or it might blow lukewarm. Eventually, it'll just stop being cold altogether. It's a pretty critical part for comfort, especially in warmer climates. If it leaks, it can also cause your AC system to lose refrigerant, making it ineffective and potentially damaging other components. You’ll notice if it’s going bad because the air won’t be as cold as it should be, or you might even smell a sweet, musty odor—that’s the refrigerant leaking.
