I have a little problem with Windshield Washer System in my Acura TSX '06. When I pull the wiper control lever toward me and hold it, the washers spray onto windshield but the wipers don't run and in order to wipe the winshield I should push the lever up or down to the fourth position. Is anybody who has had a similar problem or who knows how to solve it ?

Thanks in advance for help.
