On mine is as it should be pull the lever towards you and it washes and wipes 3 or 4 times. It was the light washers that got me. Spent ages, pulling, pushing, twisting, you name it. I had to get manual out in the end. Felt a right spanner when saw there was a seperate button, but even then it wasn't over as I didn't know the lights had to be on, so I was topping the water bottle up, checking to see if it had its own little supply. It was my neighbour over the road who has the same car as me that told me the lights had to be on.
Typical us fellas, rushing in thinking we know it all......
