Why You Might Want to Remove Your Rear Wiper
While a rear wiper serves a functional purpose, there are several compelling reasons why car owners and DIY enthusiasts choose to remove it. Understanding these can help you decide if this modification is right for you.
Aesthetics and Clean Lines
For many, the primary motivation is visual. Removing the rear wiper creates a much cleaner, streamlined look for the back of the vehicle. This is especially popular with hatchbacks, SUVs, and wagons where the wiper can interrupt the flow of the design.
It’s a subtle change that can significantly impact your vehicle’s overall appearance, giving it a custom, minimalist vibe.
Performance and Off-Road Clearance
Off-roaders and performance enthusiasts sometimes remove the rear wiper for practical reasons. On the trails, a rear wiper can snag on branches or debris, leading to damage. Eliminating it reduces one more potential point of failure.
While the weight savings are minimal, every little bit counts for some performance applications. Plus, it simplifies the rear of the vehicle, which can be beneficial in tight off-road situations.
Replacement or Repair
Sometimes, removal isn’t about modification but necessity. A broken, seized, or faulty rear wiper motor or arm needs to be removed for replacement. Learning how to take off rear windshield wiper correctly is the first step in diagnosing and repairing issues.
Whether you’re tackling a full vehicle restoration or just need to replace a faulty motor, knowing the proper procedure is key.
Gathering Your Gear: Tools for the Job
Before you begin, gather all the necessary tools. Having everything at hand will make the process smoother and more efficient. You likely have most of these in your garage already.
- Socket Wrench Set: You’ll need this for the mounting nut or bolt. A standard set with various sizes (8mm, 10mm, 13mm are common) is usually sufficient.
- Flathead Screwdriver: Useful for prying off plastic caps or trim pieces.
- Pry Tool / Plastic Trim Removal Tool: Essential for safely prying without scratching paint or breaking plastic.
- Penetrating Oil (e.g., WD-40, PB Blaster): Invaluable for loosening rusted or seized nuts and bolts.
- Clean Rags or Microfiber Cloths: For cleaning, protecting surfaces, and wiping away grime.
- Painter’s Tape or Masking Tape: To protect surrounding paint and glass from scratches.
- Optional: Heat Gun or Hair Dryer: Can help loosen stubborn parts, especially if adhesives are involved.
- Optional: Wiper Arm Puller: For extremely seized wiper arms.
Safety First: Essential Precautions Before You Start
Your safety and the integrity of your vehicle are paramount. Always take a few moments to prepare and ensure a safe working environment.
- Park on Level Ground: Ensure your vehicle is stable and won’t roll.
- Engage Parking Brake: Always activate your parking brake.
- Disconnect Battery (Optional but Recommended for Motor Removal): If you plan to remove the wiper motor or work with electrical components, disconnect the negative terminal of your battery. This prevents accidental activation and electrical shorts.
- Protect Your Paint and Glass: Place painter’s tape around the base of the wiper arm. This creates a barrier against accidental scratches from tools or the wiper arm itself. Lay a thick rag or towel over the rear glass for extra protection if needed.
- Wear Gloves: Protect your hands from grime, sharp edges, and chemicals.
- Eye Protection: Always wear safety glasses to shield your eyes from debris.
Understanding Your Rear Wiper Assembly Before You Learn How to Take Off Rear Windshield Wiper
Before you start wrenching, it’s helpful to understand the basic components of your rear wiper system. This knowledge will guide you through the process and help you anticipate potential challenges.
Arm vs. Blade vs. Motor
The wiper blade is the rubber part that actually touches the glass and wipes away water. This is usually easy to remove and replace.
The wiper arm is the metal or plastic lever that holds the blade and pivots on a spindle. This is the main component you’ll be focusing on removing.
The wiper motor is located inside the tailgate or hatch. It’s the electrical component that drives the wiper arm’s movement. Removing this requires more interior panel disassembly.
Common Mounting Styles
Most rear wiper arms attach to a splined shaft (spindle) that protrudes from the tailgate. The arm is then secured by a nut or sometimes a bolt, often hidden under a plastic cap.
Some arms might have a small clip or release lever that needs to be manipulated before the arm can be lifted or pulled off. Familiarize yourself with your specific vehicle’s design by checking your owner’s manual or looking up diagrams online.
Step-by-Step Guide: How to Take Off Rear Windshield Wiper Arm
Now, let’s get down to business. Follow these steps carefully to remove your rear wiper arm without a hitch.
Step 1: Initial Inspection and Cleaning
Before you do anything, give the wiper assembly a good clean. Dirt and grime can hide fasteners and make parts harder to move. Use a damp cloth to wipe down the area around the wiper arm’s base.
Inspect the base for any plastic caps, covers, or visible nuts/bolts. Take a mental note or even a photo of how it looks before you start.
Step 2: Lifting the Wiper Arm
Just like a front wiper, the rear wiper arm can usually be pulled away from the glass. Lift the arm until it locks into an upright position, perpendicular to the glass. This provides better access to the base.
If your arm doesn’t lock, you might need to hold it up or have a helper assist you.
Step 3: Accessing the Mounting Nut/Bolt
Most rear wiper arms have a small plastic cap covering the mounting nut or bolt. Carefully use your flathead screwdriver or plastic pry tool to gently pry this cap off.
Work slowly and evenly to avoid damaging the cap or scratching the surrounding paint. Once the cap is off, you should see a nut or bolt securing the wiper arm to the spindle.
Step 4: Removing the Fastener
Identify the size of the nut or bolt. Select the appropriate socket from your set and attach it to your socket wrench.
If the nut or bolt appears rusted or seized, apply a generous amount of penetrating oil. Let it soak for 10-15 minutes before attempting to loosen it. Turn the wrench counter-clockwise to loosen the fastener.
Be firm but gentle. Avoid stripping the bolt or snapping it. If it’s very stubborn, apply more penetrating oil and try again.
Step 5: Wiggling the Arm Free
Once the nut or bolt is removed, the wiper arm itself might still be quite tight on the splined shaft. It can often be seized due to corrosion or being on there for a long time.
Gently wiggle the arm back and forth, and try to pull it straight up off the shaft. Do not twist it aggressively, as this can damage the splines on the shaft or the arm itself.
If it’s stuck, you can try tapping the base of the arm with a rubber mallet (gently!) or using a specialized wiper arm puller. A puller creates even pressure and can free even the most stubborn arms without damage.
Another trick is to spray a little more penetrating oil directly onto the splined shaft and let it work its way in. Some DIYers also use a heat gun on a low setting to gently warm the base of the arm, which can help expand the metal slightly and release the grip.
Once the arm is off, you’ve successfully completed the most challenging part of how to take off rear windshield wiper.
What to Do After Removal: Plugging the Hole
Once the wiper arm and its spindle are removed, you’ll be left with an open hole in your tailgate or hatch. This isn’t just unsightly; it’s also an entry point for water, dirt, and exhaust fumes. You need to plug it.
Why a Wiper Delete Plug is Essential
A specialized wiper delete plug is designed to seal this opening completely. It provides a clean, finished look and, more importantly, protects your vehicle’s interior from the elements.
Ignoring this step can lead to water leaks, mold growth, and damage to interior components over time.
Choosing the Right Plug
Wiper delete plugs come in various sizes and materials, typically rubber, plastic, or even glass. Measure the diameter of the hole left by the wiper spindle to ensure you purchase the correct size.
Many auto parts stores and online retailers offer universal or vehicle-specific plugs. For a truly custom look, you might even find plugs that match your vehicle’s paint color or tint.
Installation Steps for a Clean Finish
- Clean the Area: Thoroughly clean the area around the hole on both the exterior and interior of the tailgate. Remove any grime, old sealant, or debris.
- Apply Sealant (Recommended): For an extra watertight seal, apply a thin bead of automotive-grade silicone sealant around the edge of the hole on the exterior.
- Insert the Plug: Carefully insert the delete plug from the exterior side. Ensure it sits flush and creates a tight seal.
- Secure (If Applicable): Some plugs come with a nut or washer for the interior side to secure it. Tighten these components according to the manufacturer’s instructions.
- Wipe Away Excess: Immediately wipe away any excess sealant with a clean rag before it dries.
For those diving into more advanced modifications, mastering how to take off rear windshield wiper is often just the first step towards a fully customized vehicle.
Troubleshooting Common Hurdles
Even with the best instructions, you might encounter a few snags. Here are some common problems and their solutions:
- Stripped Nut/Bolt: If the fastener is stripped, you might need to use a bolt extractor set. These tools are designed to grip and remove damaged fasteners. In extreme cases, a Dremel tool with a cutting wheel might be used to carefully cut the nut off, but this should be a last resort and done with extreme caution.
- Seized Wiper Arm: As mentioned, a wiper arm puller is your best friend here. Alternatively, apply more penetrating oil, let it soak longer (even overnight), and try the gentle heat gun method.
- Broken Plastic Cap: If the plastic cap breaks during removal, don’t worry too much. You won’t be reinstalling it anyway if you’re doing a permanent delete. If you’re replacing the arm, new arms often come with new caps, or they can be purchased separately.
- Wiper Motor Removal: If you’re removing the entire motor, you’ll need to open the interior panel of your tailgate/hatch. This usually involves removing screws, clips, and prying off the panel with a trim removal tool. Always disconnect the battery before working with the motor’s electrical connections.
Reinstallation (If Applicable) & Final Checks
If you’re only removing the wiper for repair or replacement, the reinstallation process is essentially the reverse of removal. Ensure the new arm is properly aligned on the splined shaft and that the mounting nut/bolt is tightened securely, but not over-tightened.
After reinstallation, test the wiper’s function. Ensure it moves smoothly and clears the glass effectively. Check for any wobbling or unusual noises.
If you opted for a permanent delete, double-check your delete plug. Ensure it’s watertight and securely seated. Pour a small amount of water over the area to test for leaks before driving in the rain.
Frequently Asked Questions About Rear Windshield Wiper Removal
Is it legal to remove the rear wiper?
In most places, yes, it is legal. Unlike front windshield wipers, which are legally mandated for visibility, rear wipers are generally considered an optional convenience feature. However, always check your local vehicle inspection laws or regulations to be certain, especially if you live in an area with strict vehicle modification rules.
Will removing the wiper affect my vehicle’s electronics?
If you only remove the wiper arm and plug the hole, it will not affect your vehicle’s electronics. If you remove the entire wiper motor, you might trigger a “bulb out” warning or similar fault code in some modern vehicles, as the car’s computer might expect to see a load on that circuit. This can often be resolved with a resistor or by coding out the feature, but it’s vehicle-specific.
Can I remove the rear wiper without special tools?
Yes, in many cases, you can. A socket wrench, screwdriver, and a bit of patience are often all you need. However, for stubborn or seized arms, a wiper arm puller can save a lot of frustration and prevent damage. Penetrating oil is also highly recommended.
How long does the process take?
For a straightforward removal of just the arm, it can take as little as 15-30 minutes. If the arm is seized, or if you’re also removing the motor and installing a delete plug, it could take 1-2 hours, depending on your experience level and the vehicle’s design.
What if my wiper arm is seized and I can’t get it off?
Don’t force it too much, as you could damage the spindle or the arm. Apply more penetrating oil and let it soak for several hours or even overnight. A wiper arm puller is specifically designed for this situation and is usually the most effective solution. Gentle heat from a heat gun can also help. If all else fails, a professional mechanic can assist.
There you have it! A complete guide on how to take off rear windshield wiper from your vehicle. Whether for aesthetics, off-road prep, or simply a necessary repair, this DIY task is well within reach for most car owners and weekend warriors.
Remember to prioritize safety, take your time, and use the right tools for the job. A clean rear window, free from a cumbersome wiper, can truly transform your vehicle’s look and feel. Enjoy your cleaner views and customized ride!
