What is the problem when the blower of Citroen C4L does not rotate?
2 Answers
The reasons and solutions for the non-rotation of the blower in Citroen C4L are as follows: Blower rotor obstruction: After prolonged use of the blower, excessive dust accumulation increases the friction coefficient between the rotor and bearings, causing the rotor to be obstructed or even stuck, leading to overheating and damage of the coil. Solution: After powering off, open the rear cover of the blower, add a few drops of lubricating oil (such as sewing machine oil) into the bearing sleeves at both ends of the rotor. While adding oil, gently rotate the blades until they move freely, and the blower issue can be resolved. Coil damage: Another possible reason is the absence of 220V AC input or a damaged coil. Solution: In this case, disconnect the power, separate the two lead wires of the blower from the power supply connection points, and leave them suspended (ensure the two ends of the power wires do not touch each other to avoid short circuits). Turn on the power and carefully measure both ends of the power wire with a test pen. If one end lights up and the other does not, it indicates the power input is normal, and the issue may be a damaged blower coil. If both ends light up or neither lights up, there is a problem with the power input.
When the blower of my Citroën C4L stops working, I always start by checking the simplest possible causes first. After all, I've been driving this car for several years and have encountered similar issues more than once. Common causes include a blown fuse—the easiest to check is the fuse box inside the car, located near the driver's seat. Look for the fuse marked with the blower symbol; if it's blackened or broken, simply replace it. Another possibility is a faulty blower motor. Gently tap it to see if it responds—if it hums but doesn't spin, the motor is likely seized or worn out and needs replacement. Resistor failure is also common, especially if you notice the fan speed can't be adjusted; in that case, the part needs to be replaced. Loose wiring connections or a malfunctioning control switch are also frequent issues, particularly after prolonged use. I remember the first time this happened, I tried unplugging and inspecting the connectors for cleanliness, and that fixed the problem. In short, avoid unnecessary disassembly—if you're unsure, it's best to consult a professional mechanic. Otherwise, safety risks are high, and going without AC in the summer is unbearable.
