how do windshield wiper sprayers work?
There is a small engine which pushes the water through the holes which are usually located on the hood. You have a reservoir with water next to the engine, and hoses which run to the sprayers holes. During the winter, remember to put special non-freeze liquid.
There's a little electric motor and pump usually located at the base of the wiper fluid reservoir that pumps water onto the windshield. My old Studebaker has a little rubber bellows that you mash down and let up to pump water onto the windshield. Crude by today's standards but top of the line 50 years ago.
There is a small tube that runs from the fluid receptacle to the windshield. There is a small motor that sends the fluid through the tube.
