Wiper stalk problem- connected to audio remote wire?

Had a wierd one today- the wiper stalk shorted out when using the washer jets, smoke and burning smell then' the washer stopped working.

Seems to be limited to the washer only, wipers, volume controls etc all working fine, BUT...

the radio now stays on when the ignition is off and my Parrot kit which is wired to the Cabasse under the seat doesn't start up (no power?)

So my question is, is it likely that they share a fuse somewhere?
