Good day to you all. I am new today to this site. I recently purchased a C4 Picasso from a general car trader. There are a number of issues that I would like to bring out for discussion but first would like to deal with the window washers and the cruise control. I have just had a new washer pump fitted as the old one didn't work from the time I collected the car. When the new one was installed it worked when I washed the windscreen. I left the garage and later that day washed the rear window. When I tried to wash the windscreen again the washer would not return to the front and will now only wash the rear window whether I pull the stalk or press the end of the stalk. I would appreciate any ideas please. Best regards. Mike
