Peugeot 307 - Resistor from the supply cables began to heat up.

Smoke has recently come out of the air vents. I turned off the engine and blower and it calmed down. I started rummaging and dug out a resistor from a blower to which the cables were attached. The black (probably +) cable was charred. I shortly connected the same cable to another (4 were) and the air flow returned, only a problem appeared, because the cables began to heat up. I thought maybe it can't be done and I bought a new resistor. I connected the cables, the ventilation started to work properly only that the resistor started to heat up so after just 2 seconds. Please help.

Give photos of old and new resistors [resistor].
Do you know what resistor power is?

the old man is also warming up

I will send you the photos, I am going to measure the tension now

It is air-cooled in the tunnel. In hands outside the tunnel is normal that hot. The engine turns slightly?

fan motor?

the temperature is such that you can't keep it in your hand so I think that's not the point

When you changed the cabin filter, it depends on, among others cooling this resistor. In addition, examine the electrical installation to which the blower is connected for damage (short circuit).

I changed the filter about 7 months ago.

My colleague, as the previous speakers have said, The blower's resistance must be cooled in the air tunnel by a turbine blow, it cannot be held in your hands. The turbine fan must rotate freely and have efficient bearings. The connector with connectors must not show overheated contacts and melted insulation.

I sat in the car and buried it a bit ... What is the situation? First of all, I found one cable where the resistor doesn't heat up. This is the cable from the 4th speed (plug 2nd from the right). I held the resistor and it was very good, i.e. the temperature was optimal. After connecting the next cables, the resistor was heating up very quickly. I put it back in again from which the resistor did not heat up and everything returned to normal. The blower works beautifully without any signs of smearing. The wind was blowing like in the good times. I thought that maybe I would pull it out and put it in another contact of the resistor - unfortunately the resistor immediately got warm despite the fact that the rotation of the windmill decreased. I put other cables (in turn) into the pin on which the first cable caused normal work, unfortunately each combination caused the resistor to heat up. Conclusion: ventilation normally only works at speed.

There is one conclusion - you do not completely understand the principles of this system, you have already been told that the resistor should work in the air tunnel because it is cooled in it. In the fourth gear, the resistance does not heat because it does not work, it is intended only for the first three gears.

So replace the pins and the cord.

now I understand - it was immediately written - if the heating of the resistor is normal, what temperature does it reach?
Anyway, somebody explain why after skipping the resistor, when connecting cables from level 3, are they terribly hot?

Because power has nowhere to exude. Until now, power was released in resistors giving off heat to the environment.

I just understand that someone will answer the question: is it normal that the resistor heats up to such a temperature that it cannot be kept in hand?

Of course.

I buried, connected a new resistor, repaired the faulty cables and what? Everything's fine so far. Tomorrow I will test the wind a little - I have to do about 90 km, so all that is bad will certainly be revealed. I am still surprised that heating the resistor (so much) is the norm - but I think it should be like that. Many thanks for the advice, tips and tricks. I wish it was good.

Note that the resistor assembly is stabilized by ceramic mass flooding and this is resistant to extremely high temperatures, its use indicates something.

Resistance in the air tunnel has a completely different temperature, read carefully and draw conclusions thinking does not hurt.

sure it doesn't hurt I learned in this forum that it also blows there. The most important thing is that it works. Once again, many thanks. Ps Over the next week I will be carrying an additional fire extinguisher
