The symptoms of a broken car air conditioning evaporator include the car air conditioner not cooling, the car air conditioning system lacking refrigerant, and the smell of car air conditioning refrigerant or refrigerant oil in the cabin. If the car evaporator is clogged, a car air conditioning manifold pressure gauge can be used for inspection and diagnosis. The car evaporator is located inside the dashboard. When the air conditioner is turned on, the evaporator needs to exchange heat and cold, causing a large amount of condensation to form on its surface. At the same time, outside air entering may carry various dust, bacteria, impurities, etc., which stick to the surface of the evaporator along with the condensation. Additionally, when the air conditioning evaporator is not working, it remains in a warm, dark, and humid environment for a long time, making it very easy for a large number of molds and various bacteria to grow. Once mold encounters a suitable environment, it can multiply quickly. Therefore, regular cleaning is necessary, and it is recommended to clean it once a year.
I often encounter air conditioning problems while driving. The most typical symptom of a broken evaporator is that the air conditioning doesn't cool properly, blowing out warm or room-temperature air, which makes driving on highways in summer extremely frustrating. What's worse, there's a strong musty or sour smell in the cabin, like old carpet, which is very unpleasant. Sometimes, you might notice water leaking onto the floor, soaking your shoes, because the evaporator is positioned low and accumulated water leaks out. If not repaired promptly, the smell can linger for days and may foster bacteria, leading to health issues. I once suffered from headaches until the faulty part was replaced. Overall, this significantly reduces driving comfort, so it's advisable to check the air conditioning system early to prevent minor issues from escalating.
