Why is one Honda fan spinning while the other is not?
4 Answers
Honda fan one turns one does not turn the reasons are as follows: 1. Improper maintenance: The crankshaft is short of oil, you can evenly apply engine oil (lubricating oil, etc.) on the shaft position. 2. The starting capacitor capacity becomes smaller: This is because the fan has been used for too long, resulting in insufficient motor starting torque, and the internal electrical components need to be replaced. 3. Motor overheating: Check whether the internal wiring of the fan is normal and replace the components. Information about the fan is as follows: 1. Fan: Refers to a tool used to generate wind and cool down in hot weather. 2. Working principle: The energized coil is subjected to force in the magnetic field and rotates. 3. Energy conversion form: Electrical energy is mainly converted into mechanical energy, and at the same time, because the coil has resistance, it is inevitable that part of the electrical energy will be converted into heat energy.
Once my Honda car's fan had one side working and the other not, which gave me a scare as the engine temperature started rising. Later, I found out common issues include a damaged fan motor causing one side to fail, or a blown fuse located in the engine compartment fuse box—check the manual for the fuse marked for the fan; relay failure is also a major cause, as the relay controls the fan circuit, and if one side fails, it stops working; aging wiring or loose connections, especially in older cars, can cause power loss due to corroded plugs. At the time, I checked the fuse and found it was blown. Replacing it fixed the issue safely. I suggest you quickly check the fuse yourself first—it's simple and easy to do—don’t delay, or the engine might overheat and cause costly damage. Even at a dealership, they’d start with this step to save time.
After driving for many years, I've seen many similar issues where one fan spins while the other doesn't, which directly threatens safety because it affects the cooling system's ability to dissipate heat. Possible reasons include the fan itself being rusted or worn out and stopping, a blown fuse (commonly caused by abnormal current, requiring timely replacement—located in the fuse box, don't confuse it with others), a failed relay preventing the control signal from connecting the circuit, or a short circuit breaking the current. When the fan malfunctions, immediately pull over and check the dashboard for overheating to avoid continued driving leading to engine overheating or seizure. Simple tools like a screwdriver can first check the fuse; if that doesn't work, seek help from a professional shop. Regular vehicle maintenance can prevent such issues, saving money and hassle.
As a car enthusiast, I analyze that when one fan is running while the other stops, there are usually technical reasons. The most common issue is a faulty fan motor—aging may prevent it from turning. The relay might have burnt contacts and needs testing or replacement. A blown fuse interrupts power supply—locate the corresponding color fuse in the manual's marked area. Loose wiring connections can be checked with a multimeter for continuity safely. Sometimes, a faulty temperature sensor sends incorrect signals, affecting fan activation—a reset might resolve it. Don’t worry, most cases aren’t major issues. Checking fuses or relays yourself can restore functionality and maintain cooling efficiency.
