The washer/wiper functionality has stoped working on my defender 2012; no noise or movement when I press the stalk. The wipers work in all the other modes, and I’ve checked the fuses. What would be the next logical steps to diagnose the fault? If the pump has the fault would this cause total failure and stop the wipers from activating in this mode? Or could it be as simple as the stalk has the fault which is stopping the pump and the wipers from activating in this mode?
