What is the reason for the Peugeot 308 blower not working?
2 Answers
Peugeot 308 blower not working is generally due to a problem with the blower circuit, most commonly a burnt-out resistor. Below is an extended introduction: 1. Composition of the blower: The blower mainly consists of the following six parts: motor, air filter, blower body, air chamber, base (also serving as the oil tank), and oil drip nozzle. 2. Working principle of the blower: The blower operates by the eccentric rotation of the rotor inside the cylinder, causing the volume between the blades in the rotor slots to change, thereby sucking in, compressing, and expelling air. During operation, the pressure difference of the blower automatically delivers lubrication to the oil drip nozzle, which drips into the cylinder to reduce friction and noise, while also preventing gas backflow in the cylinder. This type of blower is also known as a sliding vane blower.
My old Peugeot 308's AC blower stopped working recently, and it took me quite a while to figure it out. There are several aspects to consider. A blown fuse is the most common issue—check the corresponding blower fuse in the fuse box under the driver's seat and replace it if needed. Relay problems are also frequent; it's located near the engine bay, so try swapping it out to test. If the motor itself is worn or burnt out, it won't move at all, especially in older cars. Wiring issues like loose connectors or rodent-chewed wires can interrupt power. Faulty control switches or AC module problems require professional diagnostic tools. Whatever the cause, delaying repairs can make summer unbearable and even distract you while driving, which is unsafe. I recommend checking the fuses and relays yourself—it's quick, cost-effective, and safety comes first.
