You will need to access the 2 pin connector to do a basic voltage test.Disconnect the 2 pin connector from the pump ,with the ignition on,test the voltage at both wires.There should be around 12 volts at both the yellow/black and white/black wires.The pump is not controlled directly from the wash/wipe stalk/switch.hth

You could use a very basic test light for this job.Probably buy one for £10 or less.

Might have been better had I done that before I bought a new pump.

I fitted the pump and the system remained as dead as a dodo. I checked fuses, fiddled with connections, the lot, and having exhausted all my own avenues I called a chap with a bit more experience. Through a process of elimination and using a simple testing light, he discovered that one of the pins in the multi plug between pump wiring and main cable had corroded and snapped off, so there was no longer a connection. We butchered the plug from the circuit, twisted the wires together (I'll do a more permanent fix with cable connectors at a later date) wrapped it all in insulating tape and hey presto: washer fluid squirting all over the show.

Cheers for all advice.
