About Windshield-Washer Pumps
Windshield wipers require a windshield washer, a system that uses a pump to produce windshield water fluid, to function properly. The system allows the windshield blades to wipe the window in a fluid manner. Without the windshield-washer pump, the fluid would not be excreted and the blades would not work properly.

Significance
-
Motor vehicles use one to two windshield wipers to sweep across the front and, in some cases, rear windows of a vehicle. The sweeping motion is used to effectively wipe away rain and debris. As mandated by law, operative vehicles, such as cars, buses, trains, aircrafts and watercrafts, must be equipped with windshield wipers. This law acts to ensure that each motorist is operating his vehicle with a clear, unobstructed view of the road.
Geography
-
Hundreds of manufacturers around the world produce windshield-washer pumps, however, Trico Products is most known and respected. The Trico washer pump inventory includes 37 original equipment style 12-volt pumps, including models 11-529, 11-530 (each compatible with the Caravan, Grand Caravan, Town & Country, Voyager, and PT Crusier).

Effects
-
Most windshield washer pumps come with considerable hose length; excess length that is not used can be hidden in the box next to the reservoir tank. For easy handling, replacement windshield-washer pumps plug into the wiring of the original pump.
Considerations
-
Located on the lower side of the water tank, windshield-washer pumps produce a windshield washer fluid that lubricates and allows the sweeping motion of the windshield blades. This fluid is then used to clean bugs, dirt, grime, debris and deposits from the window. Depending on the model, most washer pump kits can produce the spray power of factory original equipment (42psi is the recommended pressure for a 1 liter reservoir). Most replacement kits are manufactured to match existing wiper systems, depending on the make and model of the car of course. Pumps are even effective in harsh cold weather, when it is necessary to loosen hard snow from a window.
Benefits
-
Windshield washer pumps are generally sold with a reservoir and pump kit. The kit is used to for the general maintenance and repair of the original and replacement equipment.
Some windshield washer pumps are exclusively for rear windows. Models with a front and rear window wiper/washer system will be marked accordingly. Verify the part number on existing unit--if replacing--prior to ordering.
Size
-
Windshield washer pumps can be purchased online at Amazon and Nextag or in a retail chain like Target from $6 for a basic manual version to $21 for a washer replacement pump kit. Commercial models like the Liquidynamics Air Double Diaphragm Pump can costs as much as $300 online.
Warning
-
Ensure proper driving safety with a new or replacement windshield-washer pump. A damaged or malfunctioning washer pump may lead to an accident due to poor visibility.
