How Does it Work? Windshield Wipers

Windshield wipers are standard on every make and model of vehicle in service today. This fascinating contraption of motor and gears can even be found on airplanes and even the space shuttle. We might take them for granted, but these wipers keep our windows clear of water and debris. It actually takes a lot of force to accelerate wiper blades back and forth so quickly. In order to create this force, a worm gear is used in connection with a small electric motor. Attached to the output shaft of the gear reduction is a short cam. This cam is attached to a long rod, as the cam spins as the wiper motor turns, the rod moves back and forth activating the wiper blades. We may not need to rely on them very ofter here in sunny Southern California, it helps if they work properly when you do need them.

It's important to properly maintain your windshield wipers if you want them to work properly. Replacing the wiper blades is the most essential and simplest way to care for them. Depending on how often the blades are used, you should replace them ever 12-24 months. When the blade is new, it easily wipes away any water without leaving any streaks. As they age, nicks and cracks form, grime builds up and interrupts the seal against the window. In this case, it may leave streaks or skid across your windshield.

Automatic Windshield Wipers

Advanced wiper technology is now allowing the wiper blades to sense when water is present by built in sensors. The sensors notify the car's computer system, which then tells the engine what, when and at what speed to turn on. General Motors was one of the first manufacturers to create a system that could see rain and activate wipers without driver input called Rainsense. The first vehicles to hit the road with Rainsense technology was the 1996 Cadillac STS, Eldorado, and DeVille. It was followed by the 1997 Buick Park Avenue. Rainsense still reigns at GM, and a large part of the manufacturers vehicle line-up includes the technology. Chrysler, Dodge, Jeep, Ram, Toyota, and Volkswagen also include similar technology in some of their models today.
