Am pulling my hair out here!!
both front and back wipers work fine but washer pump doesn't work at all; I'm not a novice so I've changed the fuses no:2 and no:17 or 18, twice
Changed the motor twice, 1 2nd hand 1 new
Checked every single fuse
Power probe to the connection to the motor; lights up
Changed the bonnet catch
Headlight washers work a dream!
It's got the rain/light sensor on the screen but seems to be working as it should
I'm going to scrap the car if I can't sort it so any help will be much appreciated

Random thoughts:- the headlight washers use a completely different pump: the command to the screen front or rear washer pump will be sent from the steering wheel controls to a controller and it will power the pump up: the control line to switch on the pump might be a "low" not a "high": probing a power feed and finding voltage when the load is not connected means nothing as if there is a high resistance on that feed, very little actual voltage will get applied to the load (been there done that - once and that was enough!)

Thanks for the reply mate, think it's auto electrician time!!!
