V70 2004 rear window washer fluid stopped working

This happened the other day after the temperatures got below freezing.
The rear wiper still works.
The front fluid and headlight fluid still works.
As I understand it, this is all from the same pump on the V70 so it cannot be a fuse.
I took the tailgate trim off and pulled off the pipe from the rear connection and then tried the lever but still no fluid comes out.
I cannot see any fluid underneath the car so it doesn;t seem like it's leaking anywhere.
Any ideas of what next to try?
Apparently there is a connection valve inside the rear panelling as per the attached diagram but I cannot seem to pull the trim off.

I took off the back tube and took a bicycle pump and pumped air through it. I can hear air coming out as bubbles in the front reservoir so there is no blockage. However, when I push the lever for the back, the wiper comes on but still no fluid. No fluid comes out of the pipe even when disconnected.

How does the fluid in the pump get directed either to the front or to the back if it is the same reservoir?
