Hi.
my A8 wipers stooped working suddenly while in use and the column arm does not pump washer fluid either.
If I pull arm towards me no fluid. nothing. If I move arm up/down as if changing wiper speed, nothing responding either.
could it be a switch in column arm ? a fuse ? other ?

any thoughts much appreciated.

 

There is a 15A fuse that operates the wipers, I'd check that first. If things look good then I'd take a look in the wiper stalk assembly and make sure the contact points are all in working order. Then I'd check the voltage running to the wiper arm motor and the windshield washer jets.
