What are the reasons for no air coming out of the Peugeot 408 vents?
1 Answers
The reasons for no air coming out of the Peugeot 408 vents may include abnormal connection of the vent switch, blown fuse of the air conditioning, blocked air vents, or malfunctioning of the air conditioning motor fan. Here are the detailed explanations: 1. Clogged air conditioning filter: The most common reason for no air coming out of the air conditioning is a clogged air conditioning filter. Since external air typically passes through the air conditioning filter before entering the car interior, the filter's main function is to isolate dust, particles, moisture, and other attachments in the air. It also provides strong sterilization and deodorization effects, ensuring that passengers do not inhale harmful gases, which could threaten health and driving safety. The air conditioning filter is usually installed above or below the blower. Therefore, air must pass through it to enter the car. If the filter is clogged, poor air circulation will naturally result in no air coming out. 2. Damaged blower: The blower is a crucial part of the air conditioning system, as the circulation of air inside the car relies on its operation. When using the air conditioning at high fan speeds, a buzzing sound can often be heard from under the passenger seat. This is the sound of the blower working—the higher the air demand, the faster the blower must draw in air. If the blower is damaged, it may not draw in enough air or stop drawing air altogether, preventing air from being blown out and causing the air conditioning to not function. 3. Faulty air door, computer, or switch: The air door is located inside the air duct and, being made of plastic, may get stuck or break. When the air door fails to open, the air drawn in by the blower cannot flow out through the vents, resulting in no air coming out of the air conditioning.
