90 300tdi screen washers not working

As title says. I have a 1994 300tdi defender 90 and the washers have stopped working. No pump motor noise, I've checked the fuses and obviously has screen wash. It has two pumps, one for front and one for rear. Neither work. Could it be a relay? I need check the wiring to see if the grounds are good but wanted to see of there is a common fault before I start (yes I'm lazy)

Stop being lazy then!
Get a test light or multi metre and see if you have power at the pump when operating the switch.
You may find you have more than one problem.
Good luck and let's us know the outcome when you have got over your bought of laziness.
