What are the reasons for the small fan not spinning in Toyota Prado?
2 Answers
Toyota Prado air conditioning electronic fan not spinning reasons and solutions are as follows: 1. Poor contact of the main control switch, causing the fan not to spin: Solution: Use a multimeter to measure the contact resistance of the main control switch. If the resistance is too high or zero, repair or replace it. 2. Damage to the fan motor coil, causing the fan not to spin: Solution: Use a multimeter to measure the contact resistance of the main control switch. If the resistance is too high or zero, repair or replace it. 3. Loose fastening screws between the fan motor and the fan blade, causing the fan not to spin: Solution: Tighten the screws between the fan motor and the fan blade promptly.
I recently encountered a situation where the small fan in my Prado's air conditioning system stopped working. Upon inspection, I found that the carbon brushes in the fan motor had worn out completely. After nearly ten years of use, it's quite common for the electrodes to wear out due to prolonged fan operation. Additionally, don't forget to check the resistor module, which controls the fan speed settings. A burnt-out resistor can result in only the high-speed setting working or the fan not working at all. The fuse is located under the steering wheel cover—it's a small blue 15A block. If it's blown, simply replace it. For wiring issues, pay special attention to the connector behind the glove box to see if it's loose or oxidized. If you're doing the repairs yourself, remember to disconnect the negative terminal of the battery before removing the glove box to avoid short circuits. If replacing these components doesn't solve the problem, the issue might be with the air conditioning control panel, in which case you'll need to take it to a professional repair shop.
