What is the reason for no air in the 1-3 gears of the car blower switch?
1 Answers
The reasons for no air in the first, second, and third gears of the air conditioner are as follows: 1. Evaporator box air leakage: If there is air leakage at the connection between the evaporator box shell and the air duct, the cold air originally released from the air conditioner vent will continuously leak from the air leakage point, resulting in a reduced air volume from the air conditioner vent. 2. Air filter: The air filter is located at the air intake of the blower. All cold or hot air blown out from the car air conditioner must pass through the air filter. However, the air filter is also prone to accumulating dirt. If the owner does not replace the air filter in time, a large amount of dust can easily adhere to the air filter, and these impurities will naturally reduce the gas flow passing through the air filter. 3. Poor sealing of the air duct: The air conditioner vent is connected to the blower via an additional air duct. If the sealing of the additional air duct deteriorates, air leakage will occur, and the air volume from the air conditioner vent will decrease.
