audi a4 b9 window problem

[fuzz1]

Any idea what can be wrong with the windows of the Audi a4 b9 most welcome

I bought an A4 in 2018 and the windows keep getting problems.

Started with the left front window where the window closes and then comes down. intermittent then permanent. Regulator was changed after
Rear right motor would continue to run after window was automatically closed was reset then goes up and comes down again. Regulator changed.

Front right goes up and comes down again. regulator changed

Now rear left goes up and comes down again.

Also when the front windows are partially up when you try to close them they go down instead. No film on any window

Any idea what could be causing these problems?

Hi.
Do you have any faults recorded in the control devices?
You’ve already tried cleaning the glass gutters and lubricating; what you’re doing is the anti-pinch function.

Yeah they are clean and very well lubricated with silicone oil.

This time fortunately it was just the window mechanism was loose. Before had to change the mechanism. Strange that all 4 got problems. Statistically highly improbable

Measure voltage at motor

either 1 old phone book or 10 new ones, try for test relearning the top of glass and use phonebook to adjust it
