Volvo V70 2006 screen washers not working

Hello all, Can any of you knowledgable people tell me where to find the front & rear screen washer fuse and relay? No mention of it in the owners manual anywhere.

I have established FUSE 34 in the passenger compartment is for the 'high pressure headlamp' washers. If I take this out the headlamp washers stop working.

I have replace RELAY FST3 - which is marked RELAY, HIGH PRESSURE HEADLAMP WASHER, just in case there was any connection.

Nowhere can I find a fuse or relay for the front and rear screen washers, and neither work - wipers OK
Any help would be greatly appreciated
