Grand vitara 11 plate washers not working

[Therolsterman]

Hi there. I was wondering if anyone knew of a common problem with grand vitara 11 plate Ddis washers.
None are working. We took the wheel arch out and put one of the pumps on a battery and it worked fine but none are working with the washer arm in the car. The wipes all work fine. I’ve looked at fuse box layouts but can’t see a separate fuse for the washer pumps.
Any tips. Then back washer hasn’t worked for ages but the front one has stopped too now.
Thanks in advance
