    The problem as in the topic, at the highest gear the fuse blows from the blower, at 3rd gear the fuse socket gets very hot. What could be the reason? I suspect there may be something with the fan itself. Has anyone had a similar problem?

    The fan is probably hard, take a look.

    What should the current be at 4th blower speed?

    Smaller than the factory fuse. If it burns it, the current is too big.
    The current depends on the power of the fan and you would have to look for such data in stores offering fans. You divide by 12 and you have the electricity consumed by the fan.
    The most common reason is a hard-rotating rotor, as colleague Ireneo wrote above.

    Ok, I understand everything, unfortunately I'm afraid of these tests, because the big fuses are burning

    Added after 4 [minutes]:

    maybe someone has a diagram for connecting this fan?

    Added 50 [minutes]:

    One more question for the blower comes the red and brown wires, earlier in the same bundle goes the red / white and brown wires to the plug, which goes on. When you disconnect this plug, the fan stops working. Does anyone know what she is from? I measured the current at full speed and came out around 21 A

    You did not specify whether there is air conditioning and what if it is.
    Diagram for normal supply with a resistor.

    Power supply from fuse No. 68 with a value of 25A.
    The power supply goes to the E9 gear switch and from it through the N24 resistor to the V2 fan.

    Artur, but why should he want to check the diagram?

    Buddy Ireneo, I forgot to write that the fan lubricated, bought another used, and the problem is still there. Tomorrow I will be testing the fan current consumption outside the installation in the car.

    Just such a small detail ... Or maybe the cabin filter is clogged with amen?

    No, this is also not a reason, because I tested the fan both in the system and in the situation in which it was pulled out.

    Added after 12 [hours] 5 [minutes]:

    I measured the current consumption of the fan itself and it goes out 20.5 A, and the fuse is 25A.

    Added after 9 [minutes]:

    It turns out that the cause may actually be on the fan side. I will measure the current in the car and I think I will make the rotation speed in 3rd and 4th gear the same.

    Hello,

    I refresh the topic. Did someone solve the problem? I also had a thermal fuse for the blower resistor, I gave a slightly larger one and is currently burning in the array. They told me in the store that it could be the fault of the heater motor. Is it possible?

    Regards

    I will join the topic, because in Fox from 2008 I do not have any power on the fuse from the blower no. 42.

    Replace the inch resistor resistor I had so in leosi I replaced the peace. Rezol was all cracked, there was a bit of shouting about it in the vaga group and they started dosing better replacements

Topic summary

The discussion revolves around a recurring issue with the blower in a 2000 Skoda Fabia, where the fuse blows at the highest gear and the fuse socket overheats at 3rd gear. Users suggest that the problem may stem from a hard-rotating fan or an overloaded circuit, as the current consumption of the fan is measured at approximately 20.5 A, close to the 25 A fuse rating. Recommendations include checking the fan's rotor, ensuring proper wiring connections, and considering the condition of the cabin filter. Some users also mention the possibility of a faulty heater motor affecting the blower's performance. Diagrams for wiring and resistor specifications are shared to assist in troubleshooting.
