Hello.

The above photo is the window control panel board in the Corolla E12. The problem is the non-working window lock, ie after pressing the "W1" button, the "D1" diode should go out and the passenger's window should not go down, but the diode does not go out. I replaced the panel from the Englishman and it is the same. I undressed, cleaned it, checked it on the desk by connecting it to the 9V battery and the diode turned off after a short circuit in "W1" and I thought the problem was solved. However, after plugging into the car's installation, the LED does not go out. The panel power supply is 12V or should it be lower, e.g. 9V, if so, where to look for the reason?
If someone had a similar problem and solved it or has an idea how to solve it, I would be grateful for your advice.
Best regards.
