What is the reason for the Toyota Prado air conditioning electronic fan not working?
2 Answers
Toyota Prado air conditioning electronic fan not working reasons are as follows: 1. Lack of refrigerant: The refrigerant naturally decreases by 0.1KG every year, and if it is insufficient, it will not work. Refrigerant leaks in the air conditioning pipeline, gasket damage, pipeline rupture, or condenser (radiator) being punctured by stones leading to refrigerant leakage. It is recommended to add refrigerant to the air conditioning system. 2. Compressor circuit issues: Blown fuse, loose wiring socket, or relay problems. Replace the relay. 3. Compressor damage: Compressor belt slipping, air conditioning pump damage, or compressor coil failure. If the compressor is damaged, it needs to be repaired at a 4S shop.
After driving a Toyota Prado for so many years, I've encountered the issue of the electric fan not spinning quite a few times. The most common cause is a blown fuse. The fuse for the fan circuit is located in the engine compartment's fuse box. Pull it out to check if it's melted, and replacing it with a new one that costs just a few dollars can solve the problem. It could also be a relay failure. The relay is responsible for switching the current on and off, and if you don't hear the startup sound, it's likely stuck. Fan motor aging and failure are also common, especially in older vehicles with over 100,000 kilometers on them. I once encountered a faulty temperature sensor where the fan wouldn't start because it didn't receive the signal, causing the air conditioning to stop cooling. When troubleshooting, start with the simplest checks: inspect the fuse and relay. If those aren't the issue, check for loose or oxidized wiring connections. A non-spinning fan not only reduces air conditioning efficiency but can also cause the engine to overheat, affecting performance. Address the problem early to avoid being stranded on a long trip.
