Why Does a Car That Has Been Used for Several Years Have Severe Odors?
1 Answers
Car odors may originate from smells produced by passengers inside the vehicle or from a dirty cabin air filter. Below are the main areas in the air conditioning system that are prone to producing odors: 1. Odors from the cabin air filter: The cabin air filter is responsible for filtering the air that enters the vehicle, and it can accumulate a large amount of dust and debris. 2. Odors from the air conditioning evaporator: The air conditioning evaporator, shaped like a thick aluminum heat sink, can also collect dust. After using the air conditioning, the evaporator, being a component where hot and cold air exchange, can accumulate moisture from condensation, leading to mold and musty smells. 3. Odors from the air conditioning ducts: The air conditioning ducts are another area where dust can accumulate. The delivery of cold air can cause moisture in the ducts, resulting in mold growth and musty odors. 4. Odors from the interior padding near the air conditioning drain: Moisture produced when hot air meets cold in the air conditioning system is expelled through the drain pipe. If the drain pipe is clogged, moisture cannot be removed in time and may even contaminate nearby interior components such as floor mats, leading to mold and musty smells.
