Why Your 2020 Honda Accord Side Mirror Needs Replacement (and Why DIY Matters)

A functional side mirror is non-negotiable for safe driving. Without it, blind spots become dangerous zones, lane changes are risky, and parking is a nightmare. Whether your mirror is cracked, shattered, or the housing itself is broken, addressing the issue promptly is crucial.

Here are a few reasons why you might be considering a 2020 Honda Accord side mirror replacement:

  • Accidental Damage: Parking lot mishaps, fender benders, or even a tight squeeze in the garage can lead to broken mirrors.
  • Wear and Tear: Over time, the mirror glass can pit or the housing can become brittle, leading to cracks or electrical issues (if your mirror has features like heating or turn signals).
  • Vandalism: Unfortunately, sometimes mirrors are intentionally damaged.
  • Electrical Malfunctions: Heated mirrors, power adjustments, or integrated turn signals can fail, requiring a full unit replacement if the internal components are inaccessible or irreparable.

Opting for a DIY approach for your 2020 Honda Accord side mirror replacement offers several compelling benefits:

  • Significant Cost Savings: Labor costs at a dealership can be substantial. Doing it yourself can save you hundreds of dollars.
  • Sense of Accomplishment: There’s a real satisfaction in fixing your own vehicle. It builds confidence and understanding of your car.
  • Convenience: You can work on your schedule, without waiting for appointments or shuttle services.
  • Learning Experience: It’s a great way to learn more about your car’s construction and how different systems integrate.

By following our guide, you’ll be equipped with the knowledge for a successful replacement.

Gathering Your Gear: Tools and Parts for Your 2020 Honda Accord Side Mirror Replacement

Before you dive in, having all your tools and the correct replacement part ready will make the process smooth and efficient. Think of it like preparing for an off-road adventure – proper preparation is key!

Essential Tools You’ll Need:

  • Plastic Trim Removal Tool Set: Absolutely essential to prevent scratching or damaging your door panel.
  • Socket Wrench Set: You’ll likely need a 10mm socket for the mirror bolts.
  • Phillips Head Screwdriver: For various screws holding trim pieces.
  • Flathead Screwdriver: Useful for prying gently or releasing clips (use with caution and protect surfaces).
  • Small Pry Tool (or another flathead): To help disconnect electrical connectors.
  • Rag or Microfiber Towel: To protect painted surfaces from scratches.
  • Work Light or Headlamp: Especially if working in a garage or on a cloudy day.
  • Safety Glasses: Always protect your eyes when working with tools and potentially shattering materials.
  • Gloves: To protect your hands.

Choosing the Right Replacement Mirror:

This is where attention to detail pays off. Honda Accords, especially the 2020 model, come with various features that can be integrated into the side mirror. When sourcing your replacement, ensure it matches your specific vehicle’s options.

  • OEM (Original Equipment Manufacturer): These are identical to the mirror that came with your car. They guarantee a perfect fit and all original features, but are typically the most expensive.
  • Aftermarket: These are produced by third-party manufacturers. They can be significantly cheaper but ensure you’re buying from a reputable brand to avoid fitment issues or electrical incompatibilities.
  • Key Features to Match:
    • Heated Mirror: Does your old mirror defrost?
    • Power Adjustment: Is it electrically adjustable? (Almost all modern Accords are).
    • Turn Signal Indicator: Does it have an LED turn signal built into the mirror housing?
    • Blind Spot Monitoring (BSM): Does it have a small icon that illuminates when a car is in your blind spot? This is a crucial feature to match.
    • Puddle Lamp: Some higher trims have a light that illuminates the ground when you unlock the car.

Step-by-Step: How to 2020 Honda Accord Side Mirror Replacement Like a Pro

Alright, let’s get down to business. This section is your detailed 2020 Honda Accord side mirror replacement guide. Take your time, follow the steps, and remember that patience is a virtue in DIY.

Step 1: Safety First – Prepare Your Vehicle

  1. Park on a Level Surface: Engage your parking brake.
  2. Disconnect the Battery: For any electrical work, always disconnect the negative terminal of your 12V battery. This prevents accidental short circuits or airbag deployment. Use a 10mm wrench for this.
  3. Protect Your Paint: Place a towel or blanket over the door sill and fender to prevent scratches during the repair process.
  4. Roll Down the Window: If possible, roll down the window on the affected door. This can give you a little more room to work and prevent the glass from being in the way.

Step 2: Removing the Interior Door Panel Trim

To access the mirror’s mounting bolts and electrical connector, you’ll need to partially remove the interior door panel. This is where your plastic trim removal tools shine.

  1. Remove the Window Switch Panel:
    • Using a plastic trim tool, carefully pry up the window switch panel. Start from one edge (usually the front or rear) and work your way around.
    • Once loose, disconnect the electrical connectors by pressing their release tabs and pulling them apart. Set the panel aside.
  2. Remove Door Handle Bezel:
    • Some models have a small plastic cover behind the door handle. Gently pry this off with your trim tool.
    • Behind this, you’ll likely find a Phillips head screw. Remove it.
  3. Locate and Remove Hidden Screws:
    • There’s usually a screw at the bottom front of the door pull handle pocket. Remove it.
    • Sometimes there’s another screw or two along the bottom edge of the door panel. Check carefully.
  4. Pry Off the Door Panel:
    • Starting from the bottom edge of the door panel, use your plastic trim tool to gently pry the panel away from the door frame. You’ll hear clips popping loose.
    • Work your way around the edges. Once all clips are released, lift the door panel straight up and off the door frame.
    • You don’t need to completely remove the door panel from the car, just enough to access the mirror area. You may need to disconnect the door handle cable and other electrical connectors attached to the back of the panel, or simply prop it up safely.
  5. Remove the Sail Panel (Inner Mirror Cover):
    • This small triangular trim piece covers the mirror’s mounting bolts. It’s usually held on by clips and sometimes a single screw. Gently pry it off with your trim tool.

Step 3: Disconnecting the Old Mirror

With the sail panel removed, you’ll see the mirror’s mounting bolts and electrical harness.

  1. Disconnect Electrical Connector:
    • Locate the main electrical connector for the side mirror. It’s typically a multi-pin connector.
    • Press the release tab firmly and pull the connector apart. Sometimes a small flathead screwdriver can help gently pry the tab.
  2. Remove Mounting Bolts:
    • There are usually three nuts holding the mirror to the door frame. Use your 10mm socket wrench to carefully loosen and remove these nuts.
    • Be prepared to support the mirror as you remove the last nut to prevent it from falling and causing further damage.
  3. Remove the Old Mirror:
    • Once the nuts are off and the electrical connector is disconnected, gently pull the old mirror assembly straight out from the outside of the door.
    • Be careful not to scratch the paint around the mirror opening.

Step 4: Installing Your New 2020 Honda Accord Side Mirror

Now, it’s time for the new mirror!

  1. Position the New Mirror:
    • From the outside of the door, carefully slide the new mirror’s studs through the holes in the door frame.
    • Hold it in place while you go inside the car.
  2. Secure with Nuts:
    • From the inside, hand-tighten the three 10mm nuts onto the mirror studs.
    • Once all three are started, use your socket wrench to tighten them evenly. Do not overtighten, as this can crack the mirror housing or strip the studs. Just snug them down firmly.
  3. Reconnect Electrical Connector:
    • Plug the new mirror’s electrical connector securely into the vehicle’s harness. You should hear a click when it’s fully seated.
  4. Test the Mirror (Before Full Reassembly):
    • Reconnect your car’s negative battery terminal.
    • Turn the ignition to the “ON” position (do not start the engine).
    • Test all mirror functions: power adjustment, heating (if applicable), turn signal, and blind-spot monitor. Ensure everything works as expected.
    • If anything isn’t working, immediately disconnect the battery and recheck your electrical connection. This is a critical step in a successful how to 2020 honda accord side mirror replacement process.
    • Once confirmed, disconnect the battery again before proceeding.

Step 5: Reassembly

Reverse the steps you took for removal.

  1. Reinstall the Sail Panel:
    • Align the sail panel and push it firmly into place until the clips engage. Reinstall any screws.
  2. Reinstall the Door Panel:
    • Carefully align the door panel over the door frame, making sure the top edge sits correctly in the window channel.
    • Reconnect any door handle cables or electrical connectors that you detached from the back of the panel.
    • Starting from the top, gently push the panel back into place, ensuring all clips align and snap in. Work your way around the edges.
    • Reinstall all Phillips head screws you removed.
  3. Reinstall Door Handle Bezel and Window Switch Panel:
    • Reinstall the door handle bezel and its screw.
    • Reconnect the electrical connectors to the window switch panel.
    • Align the window switch panel and press it firmly into its slot until it clicks into place.
  4. Final Battery Reconnection:
    • Reconnect the negative battery terminal.
    • Start your car and re-test the mirror one last time.

Congratulations! You’ve successfully completed your 2020 Honda Accord side mirror replacement.

Troubleshooting Common Problems During Your Side Mirror Replacement

Even with the best guide, things can sometimes go sideways. Here are a few common issues you might encounter during your 2020 Honda Accord side mirror replacement and how to tackle them.

  • Mirror Not Adjusting or Heating:
    • Cause: Most likely an improperly connected electrical harness.
    • Fix: Disconnect the battery, remove the door panel again, and double-check that the mirror’s electrical connector is fully seated and clicked into place. Ensure no pins are bent. If it’s still not working, inspect the wiring for any damage.
  • Door Panel Clips Breaking:
    • Cause: Over-aggressive prying or using metal tools instead of plastic.
    • Fix: This is common. Keep a small bag of universal door panel clips on hand (easily found online or at auto parts stores). They’re cheap and a lifesaver.
  • Mirror Doesn’t Fit Perfectly:
    • Cause: You might have received the wrong part, or it’s a low-quality aftermarket mirror.
    • Fix: Compare the new mirror to the old one carefully before installation. If the mounting studs or housing shape are off, you’ll need to return it for the correct part. Always verify part numbers.
  • Blind Spot Monitor (BSM) Error Light:
    • Cause: If your new mirror has BSM, it might need recalibration or the sensor wasn’t properly reconnected.
    • Fix: First, ensure the electrical connector is fully seated. Sometimes, driving the vehicle for a short period will allow the system to self-calibrate. If the error persists, you might need a professional scan tool to clear the code or recalibrate the system. This is often a good point to call a professional technician.

    • Remember, if you feel overwhelmed or unsure at any point, it’s always okay to pause and seek professional help. Your safety is paramount.

    Beyond the Install: Care and Best Practices for Your New Mirror

    You’ve done the hard work, now let’s ensure your new mirror stays in top shape. Proper 2020 Honda Accord side mirror replacement care guide extends the life of your repair and keeps you safe.

    • Regular Cleaning:
      • Use a dedicated glass cleaner and a soft microfiber cloth for the mirror surface.
      • For the housing, a mild car wash soap and water solution works well. Avoid harsh chemicals that can damage plastic or paint.
    • Gentle Operation:
      • While power mirrors are robust, avoid constantly adjusting them unnecessarily.
      • If your mirror has a power-folding feature, use it when parking in tight spaces to prevent accidental bumps.
    • Pre-Drive Checks:
      • Before every drive, quickly glance at both side mirrors to ensure they are clean, properly adjusted, and free from new damage. This is a fundamental 2020 Honda Accord side mirror replacement best practices tip.
    • Winter Care:
      • If you have heated mirrors, let them do their job. Avoid scraping ice off the mirror glass with hard tools, as this can scratch the surface or damage the heating element.
      • Clear snow and ice from around the mirror housing to allow for proper movement and visibility.
    • Parking Awareness:
      • Be mindful of where you park. Avoid areas where your mirrors are likely to be clipped by passing vehicles or pedestrians.
      • Consider parking “nose-in” in tight spots to protect the mirrors.

    A little proactive care goes a long way in protecting your investment and maintaining optimal visibility.

    Sustainable & Eco-Friendly Considerations for Your Mirror Replacement

    At FatBoysOffroad, we’re not just about fixing; we’re about responsible vehicle ownership. Your 2020 Honda Accord side mirror replacement can also be an opportunity to think sustainably.

    • Recycle the Old Mirror:
      • Many components of your old mirror, especially the plastic housing and any metal parts, can be recycled. Check with your local recycling center or auto parts store about their recycling programs.
      • The mirror glass itself might be recyclable depending on your local facilities, though often it’s considered mixed waste due to coatings.
    • Choose Quality Replacements:
      • While aftermarket parts can be cheaper, investing in a higher-quality replacement (whether OEM or a reputable aftermarket brand) often means it will last longer. This reduces the frequency of replacements and the associated waste.
      • Look for manufacturers that emphasize durability and use recycled materials where appropriate.
    • Consider Used OEM Parts:
      • Sometimes, you can find perfectly good used OEM side mirrors from salvage yards or online used parts retailers. This is a fantastic eco-friendly 2020 Honda Accord side mirror replacement option, giving a second life to a functional part and reducing demand for new manufacturing. Just ensure the part is in good condition and matches your vehicle’s features.
    • Proper Disposal of Waste:
      • Ensure any broken glass or small plastic pieces are disposed of safely to prevent injury and environmental contamination.

    Frequently Asked Questions About 2020 Honda Accord Side Mirror Replacement

    Can I just replace the glass on my 2020 Honda Accord side mirror?

    Yes, often you can. If only the glass is cracked or broken and the housing, power adjustment, heating elements, and other features are intact, you can usually buy just the replacement glass. This is typically a simpler and less expensive repair, often involving prying off the old glass and snapping in a new one. However, if the housing itself is damaged or any electrical components are compromised, a full unit replacement is necessary.

    How long does a 2020 Honda Accord side mirror replacement take for a DIYer?

    For someone with basic mechanical skills, this repair typically takes about 1-2 hours. If it’s your first time removing a door panel, budget closer to 2-3 hours to take your time and avoid breaking clips. Having all your tools ready beforehand will significantly speed up the process.

    Do I need to paint a new side mirror?

    It depends on the replacement part you purchase. Many aftermarket side mirrors come in a primed finish, meaning they are ready for painting to match your vehicle’s color. Some OEM or higher-end aftermarket mirrors might come pre-painted, but they are often more expensive. If your new mirror isn’t painted, you’ll need to have it painted professionally or attempt a DIY paint job if you have the skills and equipment.

    Will replacing my side mirror affect my car’s warranty?

    Generally, performing a DIY repair like a side mirror replacement using appropriate parts will not void your entire vehicle warranty. However, if the DIY installation directly causes a problem with another component (e.g., you damage the door wiring harness during the install), that specific damage might not be covered. Always ensure you follow proper procedures and use compatible parts to minimize any potential issues.

    What’s the difference between a driver’s side and passenger’s side mirror?

    Beyond being on different sides of the car, passenger-side mirrors in many regions (including North America) are often “convex” (curved outwards) to provide a wider field of view. This makes objects appear smaller and further away than they actually are, hence the “Objects in mirror are closer than they appear” warning. Driver’s side mirrors are typically “flat” or “plane” mirrors for a true-to-life reflection. Ensure you order the correct side for your replacement.

    You’ve now got the knowledge and confidence to tackle a 2020 Honda Accord side mirror replacement. It’s a rewarding project that saves you money and strengthens your bond with your vehicle.

    Remember, safety always comes first. Take your time, double-check your work, and don’t hesitate to consult a professional if you encounter unexpected challenges.

    Keep those mirrors clear, your vision sharp, and your drives safe. Happy wrenching from the team at FatBoysOffroad!
