What are the causes of unpleasant odors in the Baojun 510's air conditioning system?

[LeMadeline]

Baojun 510 air conditioning odor causes are as follows: Dirty cabin air filter: The cabin air filter primarily filters incoming air before it reaches the evaporator, trapping larger debris and dust particles. If these contaminants accumulate over time and develop mold, they can produce unpleasant odors. Solution: Clean or replace the cabin air filter promptly. Moldy evaporator core: The evaporator core is typically constructed with aluminum fins that have narrow gaps. Fine dust particles (too small to be caught by the air filter) and condensation from AC operation can easily accumulate in these spaces, eventually leading to mold growth. Solution: Clean the evaporator core promptly.
