Escape Rear Wiper Arm: A Comprehensive Guide

Introduction

The rear wiper arm is an essential component of your vehicle's wiper system, responsible for clearing water and debris from the rear windshield. This guide provides a detailed overview of the escape rear wiper arm, covering its purpose, construction, replacement, and troubleshooting techniques.

Purpose of the Rear Wiper Arm

The primary purpose of the rear wiper arm is to actuate the wiper blade against the rear windshield. It maintains the proper contact pressure between the blade and glass, ensuring effective removal of water, dirt, and other contaminants. This improves visibility during inclement weather or when reversing the vehicle.

Construction of the Rear Wiper Arm

The rear wiper arm comprises several components:

Base: The base anchors the wiper arm to the rear windshield through a bolt or nut.

Pivot: The pivot allows the arm to rotate up and down, following the curvature of the windshield.

Spring: The spring biases the wiper arm downwards, ensuring constant contact between the blade and glass.

Blade: The wiper blade is attached to the end of the arm and consists of a rubber or silicone element that conforms to the windshield's surface.

Replacing the Rear Wiper Arm

Replacing the rear wiper arm may become necessary due to wear and tear or damage. Here are the steps involved:

1. Locate the Wiper Arm Base: Open the rear hatch or trunk and identify the wiper arm base on the rear windshield.

2. Remove the Bolt or Nut: Using a socket wrench or pliers, remove the bolt or nut securing the wiper arm base.

3. Lift the Arm Away: Gently lift the wiper arm upward to detach it from the pivot.

4. Install the New Arm: Align the new wiper arm with the pivot and carefully slide it into place.

5. Tighten the Bolt or Nut: Secure the arm by tightening the bolt or nut until it is snug but not overtightened.

6. Test the Arm: Activate the rear wiper to confirm proper operation and contact between the blade and windshield.

Troubleshooting Rear Wiper Arm Issues

If you encounter problems with your rear wiper arm, it could be due to the following issues:

Loose Wiper Arm: Over time, the bolt or nut securing the wiper arm base can loosen, causing the arm to wobble or fall off. Check the tightness of the fastener and retighten if necessary.

Bent or Damaged Arm: Physical damage to the wiper arm, such as a bend or fracture, can affect its operation. The damaged arm may need to be replaced.

Worn Wiper Blade: A worn or damaged wiper blade can reduce the effectiveness of the rear wiper arm. Inspect the blade and replace it if it shows signs of damage or deterioration.

Electrical Faults: Electrical issues can prevent the rear wiper arm from receiving power or functioning properly. Check the wiring harness and electrical connections for any damage or shorts.

Tips for Maintaining the Rear Wiper Arm

Regularly Clean the Wiper Blade: Remove any dirt or debris that may accumulate on the wiper blade using a damp cloth or window cleaner.

Avoid Using Abrasive Cleaners: Do not use abrasive cleaners or steel wool on the wiper blade, as it can scratch or damage the rubber element.

Lubricate the Wiper Arm Base: Occasionally apply a small amount of grease or lubricant to the wiper arm base to reduce friction and ensure smooth operation.

Check the Wiper Arm Periodically: Inspect the wiper arm, base, and blade regularly for any signs of wear or damage. Address any issues promptly to prevent further problems.

By following these guidelines, you can ensure the proper functioning of your escape rear wiper arm, maintaining clear visibility and driving safety in inclement weather conditions.
