Next, make sure the wiper blade is correctly installed using the proper adapter. If the problem continues, adjust the tension by stopping the blades in the upright position.
Do-it yourself windshield wiper repair is fairly easy for even the most novice of mechanics. Commonly windshield wiper arms fail because they become loose, or rusted, and repairing them is easy enough. Like any car repair the actual process and the exact problem will vary from vehicle to vehicle, depending on how your wiper arms are attached to the vehicle. These repairs can be completed with the use of pliers, new windshield wipers, and a crescent (or adjustable) wrench. Some people may find having a ratchet set nearby to be useful as well. Typically the most common problem you will find is that one wiper moves independently (or not at all) from the other. Here is how you can repair that problem.
What is the Problem?
Ascertain the problem to determine what is going on when your wipers are turned on. If one arm moves differently (slower, erratic, or not as far as it should) than the other, it usually means that the nut connecting it to the car is loose. If the arm refuses to move at all, the arm could be broken.
Repair the Armature
Tighten the problem arm back in place or, if need be, remove the arm assembly to see if the arm itself is broken. If the arm is broken you will need to buy a new one and replace it. Pay particular attention to how the arm connects to the vehicle. Most likely your arm is just loose and can be re-tightened. Once the arm is tight, turn the wiper blades back on to see if you have alleviated the problem.
Check the Wiper Blades If the wiper blades now move correctly but they are still not clearing your windshield, then most likely the blades will need to be replaced. Replace the blades to see if that corrects your problem. If however the arm is re-tightened (or replaced) but the blades still don’t work there could be a problem with your windshield wiper linkage.
Check the Linkage
The linkage can sometimes become damaged or bent and if you turn on your wipers and they make noise, but don’t move, the problem could lie there, or the motor could be burned out. Check the linkage and make sure it has not become disconnected, or replace the linkage if it is connected and continues to not work. If the motor does not make any noise and the wipers don’t move then the problem could be something as simple as a blown fuse or circuit.
Is the Electrical Working?
Check the fuse and replace it, if needed. If the electrical system still isn’t working (no noise, no movement) then perhaps you have a problem with a wire or a circuit. In such cases you should consult an auto electrician to have the circuit replaced.
By following these steps you can quickly determine the problem and repair it, making sure your wipers are working properly and ensuring your vehicle is safe to drive in incliment weather.
Sandvik Coromant explained: The wiper technology for turning is based on a carefully developed series of radii that make up the cutting edge. On a conventional insert, the nose of the edge is just one radius. The wiper edge, however, is made up of a large, main radius complemented by several smaller radii.
Here are 2 photos showing how air flies over common sedan and hatchback:
As you'll be able to see, the car window on a sedan faces flow of air on the skin. That flow of air is employed to push raindrops down the rear glass, effectively clearing it from raindrops. On the opposite hand, behind a hatchback, the rear glasss faces quite a vacuum and so flow of air cannot clear raindrops from the car window. Instead, as you aforementioned, hatchbacks deploy rear wipers to clear the raindrops.
The windshield wiper fuse is burnt out. ... If the wiper motor fuse burns out, check for any obstructions that may cause the motor to be overloaded. Heavy snow on the wiper blades or a wiper blade or arm caught on something or snagged together can cause the fuse to blow. Clear the obstruction and replace the fuse.
Traditional framed blade stability with the sleek design of a beam blade. The Hybrid Wiper Blade combines the stability of a traditional framed blade with the sleek design of a beam blade. The Hybrid Wiper Blade features a heavy-duty aerodynamic design to ensure premium performance in any type of weather.
Traditional Blades vs. Beam Blades. Traditional wiper blades have a frame to which the blade is attached, multiple exposed parts, and limited contact points. They are generally what people put on their car and the standard for cars manufactured prior to 2000.
Lift the wiper arm away from the windshield and depress the small tab on the underside of the wiper where it meets the wiper arm. When the tab is depressed, slide the wiper blade off the arm by pulling downward. Attach the new wiper blade. Pull the wiper blade tight onto the arm.
The galvanizing zinc coating is easier to paint than uncoated steel. Steel is also the material in the small parts of wipers, such as washers, screws, nuts, springs, and brackets. The blade frame is made from aluminum. The blades are made of natural rubber or synthetic compounds.
