Front Wiper and windshield washer pump not working

[VW POLO]

Polo 1.0L 2015

HI, I've checket fuses ok
wiper motor ok
windshield washer pump ok

Rear wiper works

My though is the stalk multi function harm switch, wich I took it out and gave a good clean. put it back ,it still the same.
what could be causing this ?

now is giving an error in the airbag, I'm very sure it's not damaged, and I connected Properly...
I try the 3 seconds on and off when light shows...try disconnecting the negative of the battery, but still the same.

kindly appreciate any suggestions

If you removed the stalks, meaning removed the steering wheel it will pop an airbag fault.

Did you use contact cleaner to clean the stalks. Generous amount sprayed thru the openings.

yes , all been cleaned properly dismountled and put it back, I'M sure is not the contacts in the switch.
airbag just been reset with ANCEL VD500 from Amazon, perfect, but still the same problem with front wipers and windsheld washer pump

perhaps the stalks are defective, happens sometimes.

Can you do the output test via your diagnostic interface? Output test the washer pump. If it works then your stalks are defective.
Try spraying the rear window, push from your self and hold.

Or live data, and push the stalk and monitor if there is change in live data. If there isn't faulty stalks!
