Skoda Octavia I 98r 1.6 petrol. The airflow suddenly stopped working.

Hello,
in my skoda while driving and after long work on 4, the air supply suddenly stopped working. Currently, at any speed (1,2,3,4), there is no blow reaction. The fuse looks good. I decided to unscrew the air supply motor but I don't know how to check it "briefly".
I would like to ask for help in solving my problem.
Greetings.

Does it look or is?
If the fuse is OK, you have to look into the resistor.

After all, only 2 wires (+ and -) go to the engine, so what's the problem?

There is nothing to look into the resistor because the 4th fan speed is powered bypassing the resistor.
If after the fan is powered, it works for a short time, check what I wrote below.
Check the bulb with the ignition turned on if it turns on when it is powered from fuse no.25 and touches ground.
The fan is powered from the X contact, i.e. if there is no power supply, the wipers, the cabin airflow and the heated rear window will stop working.
If the above mentioned does not work, it may be the fault of the X contact relay.
If it works, I would check the airflow control panel.
The black and blue wire in the second pin of the 6-pin plug is the power supply to the fan switch, this should be the power supply after turning on the ignition.
Switch outputs, 6-pin plug:
- first gear, pin fifth, blue wire
- second gear, fourth pin, black and blue wire
- third gear, third pin, green wire
- fourth gear, pin one, yellow wire
The above wires should be powered depending on what gear is currently engaged.

Hello, I have the same problem with Skoda Octavia, you removed the knobs and this plastic because I wanted to replace the bulb and the bulb is good so because I checked 2 times and after replacing the bulb, the air supply 1,2,3,4 does not work for a short time, the fan works on fuses No. 25 there is electricity because I checked the 12 / 24V sample, so it was replaced with a different one.My other question in the rear left lamp, I do not have fog light on the clocks, shows the indicator that they are on, and here the fuse is good and the bulb too. And the 3rd question skoda octavia has to close the door with the remote control, but I did not get it when I bought it, can I program a new one for the controller or give it a go and put on a central locking controlled by a remote control from Allegro for PLN 40, please give me a hint
