The reason for the odor when the car air conditioner is turned on is: the air conditioning ventilation ducts are too dirty or the air filter is too dirty. The air conditioning system is a part of the car where bacteria and mold tend to accumulate. The mold is blown directly into the car through the air vents, polluting the indoor air and affecting the human respiratory tract. Methods to remove the odor from the car air conditioner include: 1. If the air conditioner has not been used for a long time and only has dust on the panel and vents, a simple wipe is sufficient; 2. If the air conditioner has been used for a long time and cannot be cleaned simply by yourself, contact the after-sales service for timely cleaning of the air conditioner.

Characteristics: Vehicle purchase tax applies a single uniform tax rate that doesn't fluctuate with the taxable amount, featuring simple calculation methods and stable burdens, which facilitates tax administration by law. It follows a single-collection system, only imposed when vehicles exit circulation and enter the consumption phase.

What are the consequences of not releasing a vehicle from mortgage?
