What causes the odor in Cadillac CT5's air conditioning?
1 Answers
Car air conditioning odors can be attributed to the following reasons: 1. Dust accumulation: After years of use, dust can accumulate inside the indoor filter and copper coils of the air conditioning system. Once a certain amount of dust builds up, it starts to produce an odor, which is then dispersed into the air when the air conditioning is turned on. 2. Moisture: After the air conditioning operates in cooling or heating mode, moisture often remains inside the indoor unit. If the air conditioning is turned off immediately without a drying or anti-mold function, this moisture persists, leading to the growth of mold over time, which naturally produces a musty smell.
