Front and rear wipers and washers stopped to work

[Bugajauzsi]

Hi gents,
I got an a3 2007 1.6
Rear and front wipers are not working either the washers. Rear wiper arm stopped in the middle of the screen. No noise if I pull or push the column stalk. Fuses are fine (41-rear wiper motor, 42 dual-washer pump). Front wipers are not moving either. I removed the rear wiper motor plug and tested for 12V. 3 legs out of 4 had live. I am not sure if that is any good.
Have not found the fuse for the front wipers yet.
Any idea what to check/test?

Thanks

I got some updates.
If I use VCDS: 09-Cent. conv. -> output test
I can make the front and rear washers work. But not the wipers. Does the wiper has any relay? Can I test the stalk somehow?

Have you fitted any new headlights at all?

[Bugajauzsi]

No, I haven't
But I have done plenty of other jobs: new exhaust flex pipe welded, all brakes around, fuel flap resistor replaced, thermostat housing replaced. These should not effect the wipers.

Did they work before any of this work was done, stalk signals ok with vcds I assume?

In measuring data, group 24: steering column switch information has different values (1,2,3,4 depends on the stalk position) but no wiper movement at all. If I select the rear wiper on the stalk this value won't change from 0.
In an other group, 09: Dual washer pump+/- are OFF, both boxes. No effect if I apply the washer function on the stalk. (I am not sure if this is the right group to test the stalk.)
I will check what job has been done before.
