Why is a windshield wiper system important?
On the surface, windshield wipers seem to be extremely simple devices, and are often not even thought about until they need replacing. However, they are extremely
useful to the driver and can make the difference between life and death in harsh weather conditions. By channeling water
and other debris from the windshield, they ensure a clear line of sight on the road ahead.
What are the components of windshield wipers?
Wiper systems include a variety of components which ensure satisfactory performance.
The washer reservoir is stored under the hood of the vehicle and contains a certain amount of windshield wiper fluid. Washer pumps are responsible for spraying
this stored fluid onto the windshield.
Inside the vehicle, the driver merely flips a switch or turns a knob which allows the fluid to flow from the reservoir to the pump via the windshield washer hose where it
is pressurized before being released. The wipers themselves usually come in pairs and create a sweeping motion against the
windshield that covers most, but usually not the entire windshield.
Usually the system can be maintained by simply keeping the fluid level high enough and the blades in working order. However, other problems may require the replacement of the
windshield washer check valve, the
washer L connector, level sensor or the
washer nozzle.
Variations
Some modern vehicles come equipped with wipers on the rear window or even individual wipers for the headlights. Other vehicles have rain
sensors which trigger the blades automatically.
All types should be checked at intervals to ensure proper working status.
