Did you know that the fluid being sprayed by your windshield washer pump isn't just water? In fact, it's a mixture of distilled water, ethanol, and soap. While each brand of fluid technically has its own proprietary mix, they are almost all remarkably similar. And if you've ever driven across country or made any long road trim during summer time, you know how valuable a full reservoir of washer fluid and a properly working washer pump are. Without them, your windshield would be covered in the carcasses of dead bugs and the droppings of birds. Additionally, spraying a frosty or ice-covered windshield also helps clear it so you can see easier. Otherwise, you'd have to wait for a rain or a car wash to get full use of your windshield.
The first windshield washers were invented in the 1930s, and offered as aftermarket and optional equipment for several decades. Now, you will find that the wiper motor and washer pump are sometimes built as one assembly. If not, the washer pump will likely be built into the fluid reservoir. But most certainly you can be sure that almost any car on the road has he ability to spray washer fluid on the windshield. And it is important to use wiper fluid or an equivalent solution (one containing alcohol) instead of just plain water. Not only will it clean better, but it won't freeze in winter. Fun Fact: prompted by observations that professional drivers were five times more likely to get Legionnaires' disease, a 2010 study in the UK found a correlation between its 75 participants and their use of just plain water in their washer fluid reservoir rather than actual washer fluid.
Replacing your windshield washer pump is not a difficult task. There are only two locations it could be: integrated with the wiper motor or at the bottom of the washer fluid reservoir. If yours is part of the motor, then you are not in luck. Typically, those have to be replaced all in one shot and are more expensive. However, if yours is at the bottom of the reservoir then the process is easy.
