Fabia II - Diagnosing Rear Wiper Motor 5J7955711: Voltage on Black & Green Wires

Hello,
The rear wiper has stopped working. On the black and green wires there is voltage when the ignition is turned on regardless of whether the handle is in the off position. or on
As soon as I give the voltage to the motor, the motor and the whole mechanism work flawlessly. The same is how I give voltage to the electronics before the motor in the socket, to the green and black cable pin, the whole mechanism work correctly.

In that case, where is the problem if there is voltage in the black and green cable plug?
Through the OBD2 interface, I could not trigger the rear wiper test, the status "unavailable"
I also transferred the entire engine to Octavia I, it seems to me that it should work, because in Octavia I there is the same motor power plug, but the engine from Fabia II will not vibrate.
Is the problem in the motor electronics or in the comfort module?

Maybe the beam in the lapel is a mess.

As a colleague writes, first check the harness connecting the tailgate with the body, most often there is a broken cable.

The cables are like new, I checked.

And what the combined switch looks like in the parameters. Can you see when the handle is in the on position?

Added after 6 [minutes]:

You have an executive module on the motor, gently solder.

The problem is the lack of weight if you have power / wires in the grommet pull firmly with a hook or pliers. Plus, that's not all. And the hatch is to be closed.

The hatch does not have to be closed, not in this model. Does the washer work?

After switching on the ignition, the + power supply should be only on pin 4, of course, on 1 ground. After switching on the wiper on pin 2 there should be mass, on the back washer on the pin 3 should appear +. The switch may be damaged.

I think that something inside the car must be damp and therefore the wiper does not work, because when the weather is dry it is no problem with the wiper.
Two days ago I turned on the heating and blowing on the ful because of the fact that I am currently sick and after a short route the wiper started to work, while today the car stopped overnight and the problem returned.
