Nissan Kicks Rear Wiper Arm Replacement

The rear wiper, often overlooked, plays a crucial role in maintaining visibility during inclement weather. This is especially true for vehicles with steeply raked rear windows or those prone to accumulating dirt and grime on the rear glass, like the popular Nissan Kicks. A malfunctioning or broken rear wiper arm can significantly impair your rear visibility, compromising safety. This article provides a clear and accessible guide to replacing the rear wiper arm on a Nissan Kicks, suitable for car enthusiasts, owners, and hobby mechanics alike.

Understanding the Importance of the Rear Wiper Arm

Before diving into the replacement process, let's understand why the rear wiper arm is important. Unlike front wipers which use a more complex linkage system, the rear wiper arm is generally simpler, directly driven by a small motor. Its primary function is to hold the wiper blade against the rear window with consistent pressure, ensuring effective cleaning. Think of it like the skeletal hand that holds the wiper blade. Without a properly functioning arm, the blade won't contact the glass correctly, leading to streaks, smears, and ultimately, reduced visibility. Imagine driving a hatchback like a Volkswagen Golf or a crossover like a Honda CR-V in a rainstorm with a faulty rear wiper – seeing clearly behind you becomes extremely difficult.

Common Causes of Rear Wiper Arm Failure

Several factors can contribute to rear wiper arm failure. These include:

Physical Damage: Accidents, impacts from debris (like ice or branches), or even forceful manual manipulation can bend or break the arm. Parking lot mishaps are a frequent culprit.
Corrosion: Exposure to the elements, especially road salt and moisture, can cause the arm to corrode. This weakens the metal, making it susceptible to breakage. Cars in coastal areas or regions with heavy snow are particularly vulnerable.
Wear and Tear: Over time, the spring mechanism that provides tension can weaken, reducing the arm's ability to hold the blade against the glass. This is similar to how door hinges on older cars like a classic Ford Mustang might start to sag.
Wiper Blade Attachment Failure: The point where the wiper blade connects to the arm can degrade. This might not be the arm itself, but if the connection is loose, it can make the arm seem faulty.

Tools and Materials Needed

Replacing a rear wiper arm is a relatively straightforward task that requires only a few basic tools. Here’s what you’ll need:

New Rear Wiper Arm: Obtain the correct replacement arm specifically designed for your Nissan Kicks model year. Check online auto parts retailers or your local Nissan dealer. Verify the part number to ensure compatibility.
Socket Set: A basic socket set with various sizes is essential. A 10mm or 13mm socket is commonly needed for removing the retaining nut.
Wrench Set: A wrench set provides alternative options for loosening and tightening nuts and bolts.
Screwdriver Set: Both Phillips head and flathead screwdrivers might be needed to pry off covers or detach components.
Pliers: Pliers can be useful for gripping and manipulating small parts.
Penetrating Oil (e.g., WD-40): Applying penetrating oil to the retaining nut can help loosen it if it's corroded or stuck.
Soft Cloth or Towel: Protect the surrounding area from scratches while working.
Optional: Wiper Arm Removal Tool: While not always necessary, a specialized wiper arm removal tool can be helpful for safely removing the arm without damaging it or the motor shaft. These are similar to the tools used to remove battery terminals.

Step-by-Step Rear Wiper Arm Replacement Guide

Follow these steps to safely and effectively replace the rear wiper arm on your Nissan Kicks:

Prepare the Area: Park your Kicks on a level surface and turn off the ignition. Engage the parking brake. Gather your tools and materials and place them within easy reach. Protect the rear window and surrounding area with a soft cloth or towel to prevent scratches.
Detach the Old Wiper Blade (If Applicable): Some replacement arms come without a new wiper blade. In this case, you'll need to carefully detach the old blade from the old arm. This usually involves pressing a release tab and sliding the blade off. Note how it's attached for reinstallation onto the new arm.
Locate and Remove the Retaining Nut Cover: Most rear wiper arms have a small plastic cover that conceals the retaining nut. Use a small flathead screwdriver or your fingernail to carefully pry off this cover. Be gentle to avoid breaking it.
Loosen and Remove the Retaining Nut: Using the appropriate socket or wrench, loosen the retaining nut that secures the wiper arm to the motor shaft. If the nut is corroded or stuck, apply penetrating oil and let it sit for a few minutes before attempting to loosen it again. Once loosened, completely remove the nut.
Remove the Old Wiper Arm: This is often the trickiest part. The wiper arm is usually attached to the motor shaft via a splined connection, which can become seized over time. Try gently wiggling the arm back and forth while pulling it outwards. If it's stuck, consider using a wiper arm removal tool. The tool applies even pressure to pull the arm off the shaft, minimizing the risk of damage. Never force the arm, as this could damage the motor or its shaft.
Clean the Motor Shaft: Once the old arm is removed, inspect the motor shaft for any corrosion or debris. Clean it with a wire brush or sandpaper to ensure a clean surface for the new arm to attach to.
Install the New Wiper Arm: Align the new wiper arm with the motor shaft and push it firmly into place. Ensure it's seated correctly and the splines are engaged. The wiper arm should be positioned so that the wiper blade will rest properly on the rear window when at rest.
Reinstall the Retaining Nut: Tighten the retaining nut securely to hold the new wiper arm in place. Do not overtighten, as this could damage the motor shaft or the arm itself. A good rule of thumb is to tighten it until it's snug, then give it an additional quarter turn.
Replace the Retaining Nut Cover: Snap the plastic cover back into place to protect the nut and provide a cleaner appearance.
Reattach the Wiper Blade (If Applicable): If you removed the old wiper blade, reattach it to the new arm, ensuring it clicks securely into place.
Test the Wiper: Turn on the ignition and activate the rear wiper. Observe its operation to ensure it moves smoothly and cleans the window effectively. Check for any unusual noises or binding. If the wiper doesn't work or moves erratically, double-check that the arm is properly seated and the retaining nut is tight.

Troubleshooting Common Issues

Even with careful execution, you might encounter a few challenges. Here's how to address them:

Stuck Wiper Arm: As mentioned earlier, a stuck wiper arm is a common issue. Penetrating oil and a wiper arm removal tool are your best allies. Patience is key.
Wiper Arm Not Seating Properly: If the new wiper arm doesn't seat fully on the motor shaft, ensure the shaft is clean and free of debris. Also, check the splines on the arm and shaft for any damage.
Wiper Blade Skips or Smears: If the wiper blade skips or smears, it might be due to a worn or damaged blade. Replace the blade. Also, ensure the arm is applying sufficient pressure to the window.
Wiper Motor Doesn't Work: If the wiper motor doesn't work at all, check the fuse for the rear wiper. A blown fuse is a common cause. If the fuse is good, the motor itself might be faulty, requiring replacement. This is less common, but possible.

Preventative Maintenance

To extend the life of your rear wiper arm and blade, consider these preventative measures:

Regular Cleaning: Clean the wiper blade and rear window regularly with a mild soap and water solution. This removes dirt and grime that can cause premature wear.
Inspect the Blade: Periodically inspect the wiper blade for cracks, tears, or wear. Replace the blade as needed, typically every 6-12 months.
Avoid Dry Wiping: Never operate the wiper on a dry window. Always use washer fluid to lubricate the surface.
Protect from Extreme Weather: In areas with heavy snow or ice, lift the wiper arm away from the window to prevent it from freezing to the glass.
