Can someone help me find the opening to the washer fluid bottle on my 9000s. I have located a cap that says washer fluid along with a little cup underneath of it, but there is no obvious sign of any bigger bottle. I have tried refilling where with fluid right where this opening is, but that resulted in all of the washer fluid pouring through to the ground. I thought that I must be empty because when I pull my wiper switch to wet the windshield, I get only air--no fluid what so ever. Can anyone assist?
