Hi guys, I would like to ask for the weird situation of my car. When I pressed the front wipers button it spray the rear windows and front wipers. and pressed the rear button for rear wipers and front sprayer. Anyone face this issue before? although this is not a quite big problem, I would like to fix it if possible. Thanks at all.

 

You have the washers connected up incorrectly. Probably the hoses are on the wrong outlets.
