What causes the blower of Chery not to rotate?
3 Answers
There are two reasons for the Chery blower not rotating: dust accumulation and coil damage. Dust accumulation: After prolonged use of the blower, excessive dust deposition increases the friction coefficient between the rotor and bearings, causing rotor obstruction or even jamming, which leads to coil overheating and damage. After powering off, open the rear cover of the blower and 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, rotate the blades until they move freely, and the blower malfunction can be resolved. Coil damage: 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 wires with a test pen. If one end lights up and the other does not, it indicates the power supply line is normal, and the issue may be a damaged blower coil. If the test pen lights up at both ends or neither, it suggests a problem with the power supply line.
I'm quite familiar with the issue of Chery's blower not working. Once when I was on a long drive, the air suddenly stopped blowing, which gave me a real scare. The most common cause is a blown fuse. You should first check the fuse box under the dashboard, locate the blower section, and see if the power is cut off. Another possibility is that the blower motor itself is faulty. Over several years of use, the motor can wear out, causing it to jam or hum when powered. There's also the issue with the resistor, which controls the fan speed. If it fails, the entire system stops working. Additionally, aging control switches or loose plugs can interrupt the current flow. In the worst cases, a short circuit can damage more components. My advice is to stop the car immediately when you notice the problem and avoid forcing it to run, as it could compromise safety. Get it to a repair shop as soon as possible for replacement parts. The repair isn't expensive but is quite important, especially since no AC in summer is unbearable. Regular maintenance checks, including voltage tests by a mechanic, can help prevent such issues.
If the blower isn't working, I've fixed it myself a few times. Don't rush—start with the simple checks first. A blown fuse is the most common issue; check the manual for the fuse location and try replacing it. If the blower motor is stuck, not turning, or overheating, the carbon brushes might be severely worn, requiring a new motor. A faulty control module can also cause this—use a multimeter to check if the voltage is normal. Inspect the wiring connections for oxidation or looseness, especially if the plugs are corroded, as this can affect contact. Also, check if the blower resistor is burnt out, causing the fan speed settings to fail. Remember to turn off the power before working to avoid electric shock. After fixing, clean the air intake to prevent dust buildup and extend its lifespan. These parts are relatively prone to failure in Chery models. Replacing components yourself can save hundreds, but be careful not to mess it up.
