What Is Wiper Arm?

Do you know how important a wiper arm is? Well, Parts Avatar has covered all the information you need to know. The windshield wiper arms are essential as they grip the wipers in the required position through the entire range of motion. They are geared on one end to take the motor that supposedly drives the wipers while the other end has more than one clip designs. The windshield wiper arm gets attached tightly into the clip so that it can remain tucked between the windshield wiper arm and the windshield.

How Do Wiper Arm Work?

Power reaches the windshield wiper motors from one of two paths, when the windshield wipers actuate and the switch sends a signal through the fuse or a relay. The motor starts moving back and forth as per the driver’ needs when it reaches the windshield wiper motor. The wiper blades drag the liquid off the glass as soon as the motor turns the wiper arms that are connected to the motor.

Symptoms Of Bad Wiper Arm

It is only because of the windshield wipers that the windshield remains free of rain, snow, grit and debris. Although, the entire thing will be a failure if the wiper blades don’t receive the right assistance from the windshield wiper arm. Generally situated under the engine hood (and directly in front of the dashboard), the wiper arm is connected to the windshield wiper motor. It is because if this entire procedure that the driver is able to see properly and drive safely.

 

Well, these wiper arms are composed of durable metals that include steel and aluminum. These are designed to endure constant use and harsh weather. Although, they are designed to last a lifetime, an unforeseen situation may end up damaging the wiper arms. So, if the wiper arms of your vehicle are damaged, you are likely to notice the following symptoms:

 

  1. The paint starts flaking from the wiper arm - Generally, wiper arms are painted with black protective powder that helps it withstand the elements. Although durable, at times it may start flaking or wearing down off the wiper blade arms. So, when the paint washes off, the metal is exposed leading to rust or metal fatigue, ultimately leading to damage being caused to wiper arm. If noticed immediately, the wiper can be repaired rather than simply being removed.
  2. The windshield gets streaked - The dirt and other materials are properly cleaned when the wiper blades function in order while damaged ones can lead to the blades bowing in or out. This can lead to streaks on the windshield. In case you notice steaks, note that the wiper arm is not getting the required tension on the blade that helps in keeping it across the windshield.
  3. The windshield wipers chattering - In case you encounter the blades chattering as the wiper arms go across, then take this as a warning. The reason behind this includes improperly lubricated wiper blades or cracked windshields. Change your bent wiper as soon as possible if you notice the windshield wiper blades chattering or running roughly.
  4. Failed contact between the wiper shield and the wiper blades - This is also indicative of an underlying issue with the windshield wiper arm that is present. When the blade fails to establish a contact with the windshield, a bent wiper arm (usually upwards) should be suspected. This leads to failure in maintaining the right pressure to keep the blade edge on the windshield. So, make sure that both the wiper arms and wiper blades are working well in synchronization.
  5. No movement in the wiper blades after actuation - Mostly, this symptom is indicative of a problem with the wiper motor, but at times, the wiper arm can also trigger this problem. It happens due to stripped, lose or broken wiper arm attachment. In such cases, you are likely to hear the motor running without any actual movement in the wiper blades.
