What are the reasons for the small fan not spinning in Toyota Prado?
4 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.
If the small fan in an old Land Cruiser isn't spinning, it's most likely a resistor issue, especially when there's no response at gears 1-2. I've disassembled the blower assembly before - it's located above the passenger footwell, just remove four screws to take it out. First test the motor's power supply by directly connecting two wires from a 12V battery to the fan socket. If it spins, the motor is fine. Then check the BLOWER labeled fuse in the fuse box. The wiring connectors tend to accumulate dust and oxidize - sandpaper the contact points. A less common issue I've seen is fan blades jammed by leaves - just disassemble and clean them. If the problem occurs right after car washing, focus on checking for water ingress and short circuits in the wiring harness. Don't delay fixing this - a non-spinning fan can cause evaporator frosting, leading to more expensive repairs.
For a Toyota Prado's blower not working, start troubleshooting from the power source: First, check if the No. 40 fuse in the engine compartment fuse box is blown (20A yellow), then inspect the No. 7 fuse in the cabin. The relay is located behind the glove box—perform a tap test to see if it engages. If the low-speed setting fails while high speed works normally, this typically confirms a faulty blower resistor, which is integrated into the air duct housing. Remember to measure the voltage at the resistor connector—no reading indicates a control panel issue. To remove the resistor module, unscrew three Torx screws; avoid prying the housing open. Prolonged low-speed operation can cause motor carbon buildup and jamming, in which case the entire blower assembly needs replacement.
