Wipers work, washers don't

Those are the symptoms. Any ideas? Tried the fuses, and gave the switch a quick jiggle - no time for more - and set of with a drinks bottle full of water as an emergency washer. Checked a few threads, but no joy.

It's either the switchgear or the pump.

Simple to diagnose. Disconnect power plug on pump, put multimeter ( or bulb on two bits of wire ) onto plug, get operative to work switch. If there is power getting there it's the pump. If not its the switchgear .
If its the pump take it out and you maybe able to resurrect it by cleaning it out and de-corroding the terminals
If its the switchgear same applies , cleaning it up may fix it

There is a light chance it maybe the wires or the plug, but more often than not its either the pump or the switch

Double check by adding power to the pump before removing ?
