How to Replace Windshield Wiper Blades
A windshield wiper
is a component on a vehicle that is designed to remove rain, debris, and moisture
from the windshield. Wipers are created with corrugated ridges to maximize the wiping
action. When a windshield needs to be cleaned the windshield wipers along with washer
solvent can be effective in removing dirt and road grime. Windshield wipers are
standard equipment on almost all vehicles.
Windshield wipers are designed to operate in different modes, 2 to 4 wiper speeds,
and intermittent operation that allow adjusted intervals. Some vehicles are equipped
a rear wiper, typically a single wiper that is designed to clean the center of the
window. Windshield wipers are operated from an
using a series of connecting arms or linkage.
If the wipers system is not operational check the
first. Always replace
the fuse with the manufacturer recommended replacement. If the wiper motor is operating
but the wiper arms are not moving the linkage connected to the wiper motor has become
disconnected. Disassemble to inspect linkage, repair as needed then reassemble and
recheck system. Check the windshield wipers at least every six months and replace
Do not allow the wipers to become cracked or separated because the metal frame
that holds the wipers can damage the windshield. Inspect the
windshield washer reservoir fluid level
and refill as needed. This fluid or solvent is used to lubricate and clean the windshield
while the wipers are in use. Avoid using your windshield wipers to remove ice from
your windshield in the winter; this can cause damage to the wipers. To remove ice
from the windshield an ice scraper should be used. Anytime wiper blades are not
performing properly they should be replaced, visibility as well as safety relies
on having wipers that are in good working order.
Replacing wiper blades
is a quick and easy process; most can be changed by releasing a clip.
---Wipers are control and powered by a wiper arm and motor mechanism
with control arms connecting to the wiper pivots. A twelve volt motor is used to
supply power to the wiper system. Most wiper systems are designed with two main
pivot points that protrude through the body so the wiper arm can be attached.
Connected to these pivots are arms that attach to the wiper motor. A wiper
motor contains an armature, park mechanism and electronics that control mode
selector i.e. park, three to five variable speeds and pulse modes. A electronic
switch a speed control determine how fast and in which mode the wipers will
operate in. These modes can vary from high speed operation to just one swipe in
thirty seconds.When the wipers are demanded to operate in a duration pattern, duration meaning
the time the wiper is parked in the down position it is called "pulse" or "pulse
wipers". Some cars have been designed with an automatic rain sensing system that can measure
the amount of rain is on the windshield and will adjust the wiper operation according
to volume of rain at any giving time. This RSS system is handy when the amount of
rainfall in a given storm varies greatly by allowing the driver to keep their attention
on the road and not fiddling with a wiper switch.
