I have a 407 SW 2.0 2006 model with 48t km on it. It seems like the reservoir for the windscreen washer is leaking, when I try to top it up I can see the fluid leaking from under the car, but when I put like appr. 2 liters on it then it seems like it is not leaking off. But eventhough there should be these 2 liters in the reservoir, nothing comes out of the nozzles....? I can hear the pump like it is pumping but nothing happens.. Is there any way of inspecting this? I was trying to find a way to take the reservoir out for inspection but can not find any way to do it, any ideas??
