hello, have an audi a4 b6 model, and all power windows stopped working. I checked fuses, door wires, the wires from the comfort module and I found nothing.
central locking work,lamp door work , lamp foot too.
I did a test VAG-COM, but I did not found errors.
I searched the forum but nothing helped me
same thing happened in the past but recovered itself.
Now I'm stuck with all the windows blocked and can not find any problems.

some advice?

Thanks a lot
This is my first post on the forum

 

Try operating your windows individually, if they work from each other control then you new a new one of these. If that doesn't work, then you might need one of these, but this would read as an implausible signal for ALL of your interior electronics so I think it's just the master switch. If it's not the switch, it could just be the wires connecting the door to the body of the car.

 

Thanks for the reply.
windows do not work from any swich. door wires seem to be ok, I have lights in door, mirrors work, central locking work from remote.
I do not think it's any comfort module.

I attached a picture of motor driver side windows. I measured with a voltmeter and i have power, but when i press the swich nothing happens
If this window motor is down why the rest of the windows does not work.
relays on this board works, but only make noise when using central locking.

many thanks

 

Try opening all your windows with your key, if they open then get another switch. If they don't then it would be all four motors... I could very well be the one motor on the driver side, but don't rule out the switch quite yet.

 

hello again,
I have not found the problem yet, but I remembered only that the problem occurred when making a diagnosis with VAG-COM. I was in the car, run the VAG-COM and opened the the window to smoke a cigarette. After I finished the test I disconnected interface and wanted to close the window but I could not.
I took off motor window and got up the window manually.
Something strange in all this.

When this happened in the past, I was the same with the VAG-COM to look why not go heating in the passenger seat. But the next day I noticed that I could go down the window again. This time not happens and it's already been a week since

Can the VAG-COM software to block something?

thanks

 

nobody has any idea?

 

Change your switch... Before you start getting into a whole world of trouble...

 

I changed the switch today but nothing happened.
I will try to change module from drivre door, maybe something will happen.

thanks

 

Then it should be a loose wire somewhere on the connector. If it were the module you would have a problem accessing it with the VAG-com

 

hello,
I changed the module, but nothing has changed.
I need if anyone can help me with a wire diagram for power windows.
I want to see which wires are for windows and measure and check the continuity

thanks
