What are the reasons for the non-rotation of the Toyota Prado air conditioning fan?
3 Answers
Toyota Prado air conditioning fan not rotating may be due to a faulty fan motor or capacitor; it could be a malfunction in the motor's coil; there might be poor contact in the main control switch; the screws between the motor and the fan blade may have loosened; or the compressor might be damaged. Any of these reasons can cause the fan to stop rotating. 1. Safety of air conditioning installation: Before installation, check if the wall is sturdy. If the wall is not sturdy and has issues like peeling, there is a risk of the air conditioner falling after installation, which not only damages the unit but also poses significant safety hazards. 2. Air conditioning installation position should not be too low: During installation, the position should not be too low. If installed too low, when the cooling function is activated, the cold air will flow downward, making it difficult to achieve ideal cooling for the entire room, which also consumes more electricity. Generally, the air conditioner should be installed at the upper part of the wall to ensure even cooling or heating throughout the room. 3. Correct wiring of the air conditioner: During wiring, connections should be made strictly according to requirements. Incorrect or reversed wiring can lead to short circuits, electric shocks, and other accidents. If the wiring is altered, it can increase the load on the circuit, even leading to fire accidents.
Recently, my Toyota Prado also had this issue—the AC electric fan stopped working. There are quite a few possible causes: the most common ones are aging or burnt-out fan motors and blown fuses, especially in summer when the load is high and prone to problems. Circuit shorts or open circuits could also be the culprit—like in my case, it was poor wire contact that prevented current from flowing. Burnt-out relays are also quite common, as they can affect the fan control signal. Sensor failures, like a malfunctioning temperature sensor, can cause the fan to misjudge and not start. If the electronic control module fails, the entire system shuts down. I recommend starting with the basics, like checking the fuses, before heading to a professional shop to diagnose deeper issues. A non-functioning fan will cause the AC to fail, making the cabin uncomfortably hot, and the engine might overheat—so it’s best to get it fixed promptly.
My Prado's AC fan sometimes stops working, sharing some personal insights on possible causes. The most straightforward reason is a burnt-out fan motor, as prolonged use leads to wear and aging. Blown fuses are also common—once, high temperatures on the road caused an overload, instantly burning the fuse. Wiring issues like loose connectors or corroded wires can cause an open circuit, while burnt relay contacts may interrupt signals. Another possibility is a faulty control unit, which manages fan operation; if it fails, commands become erratic. Remember, a non-working fan increases the compressor's load, potentially causing refrigerant leaks, and long-term neglect can lead to greater damage. Regular maintenance and checking wiring can prevent issues. Before heading to the shop, I often inspect the fuse box first to confirm.
