Electric Windows fail 9n3


Recommended Posts

Hello,

For a few months, the passenger window on my VW polo 9n3 has started to fail.

He started failing randomly (he didn't go up or down) until he finally stopped failing.

I only get them to work by unplugging the battery and plugging it back in and up / down for about 10 minutes and only from the passenger side (the one that fails).

I have already tried to change the motor on the right side, comfort module and button panel on the left side (the main one).
And I also review the installation an electrician without finding anything strange. (That is not a small matter that it works only a few minutes when disconnecting the battery)

Additionally, the diagnosis is not recognizing the car, it marks the voltage but it does not go beyond there, it does not recognize the modules. I have tried several diagnoses (one official VW and another generic)

Can you think that it could be?

Thanks in advance.
