How to Solve the Problem of Foul Odor When Turning on the Car's Air Conditioning?
1 Answers
To address the foul odor when turning on the car's air conditioning, start the car, turn on the air conditioning, switch to the external circulation mode, spray a dedicated air conditioning cleaner towards the blower, close the windows and doors, switch from external to internal circulation, and let the air conditioning run for a few minutes. The foul odor when turning on the car's air conditioning may be caused by dirty air conditioning ventilation ducts or a dirty air filter. Prolonged use of the air conditioning evaporator can also lead to foul odors due to dampness and mold. It is recommended that drivers turn off the air conditioning five minutes before reaching their destination and switch to natural air. This allows the temperature inside the air conditioning ducts to rise before parking, restoring it to normal temperature. This prevents condensation due to temperature differences after parking, keeping the air conditioning ducts dry and preventing the growth of mold and fungi. Regularly replace the air filter. A dirty filter not only fails to perform its original function but also causes secondary pollution to the air entering the car. To completely eliminate odors inside the car, it is essential to address the source. Under normal conditions, an original air filter has a lifespan of one year or 30,000 kilometers. If the car is frequently driven in areas with poor air quality, the replacement cycle of the filter should be shortened accordingly.
