Why Your 2018 Honda Accord Side Mirror Needs Replacing (And Why DIY Rocks!)

Driving without a fully functional mirror significantly compromises your ability to see traffic around you, increasing the risk of accidents. For your 2018 Honda Accord side mirror replacement, understanding the “why” can motivate your DIY spirit.

Common reasons for needing a replacement include:

Impact Damage: Parking lot mishaps, fender benders, or even stray objects on the road can shatter the mirror glass or break the housing.
Motor or Heater Failure: Over time, the internal motors that adjust the mirror or the heating elements that de-fog it can fail.
Casing Damage: Cracks or breaks in the plastic housing can lead to water intrusion, further damaging internal components.
Wear and Tear: While less common for mirrors, prolonged exposure to elements can degrade the finish or seals.

The benefits of 2018 Honda Accord side mirror replacement yourself are clear. You save a significant amount on labor costs, gain valuable mechanical experience, and ensure the job is done to your satisfaction. It’s also a fantastic way to deepen your understanding of your vehicle.

Gearing Up: Tools and Parts for Your 2018 Honda Accord Side Mirror Replacement

Before you start tearing into your car, proper preparation is key. Having all the necessary tools and the correct replacement part on hand will make your 2018 Honda Accord side mirror replacement go smoothly. This is one of the most important 2018 Honda Accord side mirror replacement tips we can offer.

Identifying the Right Replacement Mirror

The 2018 Honda Accord comes in various trims, and side mirrors can differ significantly. You need to know what features your current mirror has:

Heated Mirror: Does your mirror have a heating element to de-ice or de-fog?
Power Adjustment: Most modern cars have this, but confirm.
Turn Signal Indicator: Is there an LED turn signal built into the mirror housing?
Blind Spot Monitoring (BSM): Look for a small icon on the mirror glass or a sensor on the housing. This is a crucial feature that requires specific wiring.
Color: Do you need a primed mirror for painting, or a pre-painted one that matches your car’s color code?

Always get your VIN (Vehicle Identification Number) ready when ordering. This ensures you get the exact match, whether you choose an OEM (Original Equipment Manufacturer) part for perfect fit and function, or a high-quality aftermarket alternative to save some cash. Be aware that some aftermarket mirrors may require painting to match your vehicle’s specific color.

Essential Tools for the Job

You won’t need a full mechanic’s garage, but a few specific tools will make the job much easier. Here’s what you should have ready:

Socket Wrench Set: You’ll likely need 10mm and 12mm sockets.
Phillips Head Screwdriver: For various screws holding trim and components.
Flathead Screwdriver: Useful for prying, but use with caution to avoid damage.
Plastic Trim Removal Tools: This is critical! These specialized tools prevent scratches and breaks when prying off interior door panels. Do not skip these.
Flashlight or Headlamp: To see into dark crevices.
Clean Rag or Microfiber Cloth: For cleaning up and protecting surfaces.
Painter’s Tape: To mark positions or protect paint if needed.
Work Gloves: To protect your hands.
Small Container: To keep screws and clips organized.

Having these items ready before you begin will prevent frustrating pauses in your project and contribute to the 2018 Honda Accord side mirror replacement best practices.

Step-by-Step: How to Replace Your 2018 Honda Accord Side Mirror

Now for the main event! This detailed 2018 Honda Accord side mirror replacement guide breaks down the process into manageable steps. Remember to work patiently and carefully.

Safety First: Preparations

Park on a Level Surface: Ensure your car is on stable ground and the parking brake is engaged.
Disconnect the Battery: This is a crucial safety step to prevent accidental electrical shorts or airbag deployment. Disconnect the negative terminal of your car battery using a 10mm wrench.
Gather Your Tools: Lay out all your tools and the new mirror within easy reach.

Door Panel Disassembly

Accessing the mirror bolts requires removing part of the interior door panel. This is often the most daunting part, but with trim tools, it’s straightforward.

Locate Fasteners: Look for screws hidden behind plastic caps, in door pulls, or under rubber mats in storage pockets. For the 2018 Accord, you’ll typically find screws behind the door handle trim and inside the armrest pocket.
Remove Door Handle Trim: Carefully pry off the small plastic trim piece around the interior door handle using your plastic trim tool. There might be a screw or two behind it.
Remove Armrest Screws: Pop off any rubber mats or caps in the armrest to reveal screws. Remove them.
Pry Off Door Panel: Starting from a corner (usually the bottom or front edge), gently insert your plastic trim tool and pry the door panel away from the door frame. You’ll hear clips popping. Work your way around the perimeter.
Disconnect Cables and Wires: Once the clips are free, the door panel will be loose but still attached by cables (door handle, lock) and electrical connectors (window switch, speakers). Carefully disconnect these. You may need to push tabs or slide connectors. Set the door panel aside in a safe place.

Removing the Old Mirror

With the door panel off, the mirror assembly is now accessible.

Locate Mirror Bolts: Inside the door frame, usually behind a small triangular plastic cover or trim piece near where the mirror attaches, you’ll see three bolts (typically 10mm or 12mm) holding the mirror in place.
Disconnect Electrical Connector: Trace the wiring harness from the mirror into the door. There will be an electrical connector that powers the mirror’s features. Disconnect this by pressing a tab and pulling gently.
Support the Mirror: Before removing the last bolt, make sure to support the mirror from the outside so it doesn’t fall and get further damaged (or damage your car’s paint!). You might have a helper or use painter’s tape to secure it temporarily.
Remove Bolts: Using your socket wrench, carefully remove the three bolts.
Remove Old Mirror: Gently pull the old mirror assembly away from the door. Guide the wiring harness through the opening.

Installing Your New Mirror

Installation is essentially the reverse of removal.

Position New Mirror: Carefully guide the wiring harness of the new mirror through the opening in the door frame. Align the new mirror assembly with the bolt holes.
Secure with Bolts: Insert and hand-tighten the three bolts. Once all are in place, snug them down with your socket wrench. Do not overtighten, as this can crack the plastic housing.
Connect Electrical Harness: Plug the new mirror’s electrical connector securely into the car’s wiring harness. Ensure it clicks into place.

Reassembly and Testing

Before putting everything back together, perform a quick test.

Reconnect Battery: Reconnect the negative terminal of your car battery.
Test Mirror Functions: Turn on your car (or at least accessory power) and test all mirror functions:
- Power adjustment (up, down, left, right).
- Heated mirror (if applicable – may take a few minutes to feel warmth).
- Turn signal indicator (if applicable).
- Blind spot monitor (if applicable – check for warning lights on your dash).
If any function isn’t working, immediately disconnect the battery and recheck your electrical connections. This is a crucial step in ensuring a successful how to 2018 Honda Accord side mirror replacement procedure.
Reattach Electrical Connectors to Door Panel: With functions confirmed, reconnect all electrical connectors and cables to the interior door panel (window switch, door lock, speaker, etc.).
Reinstall Door Panel: Carefully align the door panel with the door frame, making sure all clips line up. Gently push the panel back into place, working your way around the perimeter until all clips snap securely.
Reinstall Screws and Trim: Replace all screws you removed earlier (armrest, door handle) and snap the plastic trim pieces back into place.
Final Check: Give the door panel a gentle tug to ensure it’s secure. Open and close the door to confirm smooth operation.

Congratulations! You’ve successfully completed your 2018 Honda Accord side mirror replacement. Take a moment to appreciate your handiwork.

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

Now that your new mirror is installed, a little care and attention can ensure its longevity and continued perfect function. Adhering to these 2018 Honda Accord side mirror replacement best practices will keep you safe on the road.

Post-Installation Checks and Adjustments

Mirror Adjustment: Once you’ve driven a bit, fine-tune your mirror angles. Remember the “1/4 car” rule: when adjusted correctly, you should barely see the side of your own car in the innermost edge of the mirror. This minimizes blind spots.
Tightness Check: After a few drives, give the mirror housing a gentle wiggle. If it feels loose, the internal bolts might need a slight re-tightening.
Electrical Performance: Periodically check all electrical functions – adjustment, heating, turn signals, and BSM. Early detection of issues can prevent bigger problems.

Extending Your Mirror’s Lifespan

Preventative measures go a long way in avoiding future damage:

Careful Parking: Be mindful in tight parking spots or when parking near busy streets. Fold in your mirrors manually if your Accord has this feature, especially in high-risk areas.
Regular Cleaning: Keep the mirror glass and housing clean from road grime, bird droppings, and sap. Use automotive-specific glass cleaner and a soft microfiber cloth. Avoid harsh chemicals that can damage plastic or painted surfaces. This is a key part of your 2018 Honda Accord side mirror replacement care guide.
Winter Protection: In icy conditions, avoid scraping ice directly off the mirror glass with hard tools. Use a de-icer spray or your mirror’s heating function.

Sustainable Choices for Your Replacement

As off-roaders and DIYers, we often think about the impact of our choices. When considering a sustainable 2018 Honda Accord side mirror replacement, here are a few points:

Recycle Old Parts: Many auto parts stores or recycling centers accept old plastic and metal car components. Don’t just toss your old, broken mirror in the trash. Look for local options for eco-friendly 2018 Honda Accord side mirror replacement disposal.
Consider Refurbished Parts: For some components, a professionally refurbished part can be a good option, reducing waste and often saving money. While less common for mirrors, it’s worth exploring for other repairs.
Longevity: Choosing a high-quality replacement part, whether OEM or a reputable aftermarket brand, means it will last longer, reducing the frequency of replacements and overall material consumption.

Troubleshooting Common Problems After a 2018 Honda Accord Side Mirror Replacement

Even with the best intentions and careful work, sometimes minor issues can crop up. Knowing how to troubleshoot common problems after a 2018 Honda Accord side mirror replacement can save you headaches.

Electrical Glitches

Mirror Not Adjusting/Heating:
- Check Connections: The most common culprit. Disconnect the battery, remove the door panel, and ensure the mirror’s electrical connector is fully seated and not bent.
- Check Fuses: Consult your owner’s manual for the fuse box location and the specific fuse for your side mirrors. A blown fuse can cut power to the mirror.
- Wiring Damage: Inspect the wiring harness for any pinches or cuts that might have occurred during reassembly.
Blind Spot Monitor Malfunction:
- Sensor Alignment: BSM sensors are precise. If the new mirror isn’t perfectly aligned or if the sensor itself was damaged or poorly manufactured, it might trigger a warning.
- Recalibration: Some complex systems may require a dealership or specialized shop to recalibrate after a replacement. Check your owner’s manual or a service manual.

Loose Fit or Rattling

Loose Bolts: Re-check the three mounting bolts inside the door frame. Ensure they are snug, but again, avoid overtightening.
Improper Door Panel Reinstallation: If the door panel clips aren’t fully engaged, it can cause rattling. Gently push around the perimeter of the door panel to ensure all clips are seated.
Aftermarket Fitment: Some aftermarket mirrors might not have the exact same tolerances as OEM parts, leading to a slightly less snug fit. If the rattle is minor, sometimes a thin piece of weatherstripping foam can help.

When to Call a Pro

While a 2018 Honda Accord side mirror replacement is very DIY-friendly, there are times when it’s best to consult a professional:

Persistent Electrical Issues: If you’ve checked fuses and connections and the mirror still isn’t working, there might be a deeper wiring issue or a faulty new part.
Advanced Features Not Working: Features like blind spot monitoring or power-folding mirrors can be complex. If they don’t function after replacement, professional diagnosis might be needed.
Accidental Damage: If you accidentally break a window, damage the door frame, or create a significant scratch during the process, a body shop or mechanic might be the best route.

Don’t hesitate to seek expert help if you’re out of your depth. Your safety and the integrity of your vehicle are paramount.

Frequently Asked Questions About 2018 Honda Accord Side Mirror Replacement

How long does a 2018 Honda Accord side mirror replacement typically take?

For a DIYer with basic mechanical skills, a 2018 Honda Accord side mirror replacement usually takes between 1 to 2 hours. This includes setup, removal of the old mirror, installation of the new one, testing, and reassembly of the door panel. First-timers might take a bit longer, so plan for a relaxed afternoon.

Do I need to paint a new side mirror?

It depends on the replacement mirror you purchase. Many aftermarket mirrors come primed and ready for paint, meaning you’ll need to have them painted to match your car’s color. Some higher-end aftermarket or OEM mirrors might be available pre-painted. Always check the product description carefully before buying.

Is it hard to replace a side mirror on a 2018 Honda Accord?

No, it’s generally considered a moderate DIY task, not overly difficult. The trickiest part for most people is carefully removing the interior door panel without breaking any clips. With the right plastic trim tools and patience, it’s very manageable, making the how to 2018 Honda Accord side mirror replacement accessible to many.

Can I drive with a broken side mirror?

While you might legally be able to drive with one functioning side mirror (depending on local regulations, often requiring at least two mirrors, including the rearview), it is highly unsafe. A broken or missing side mirror severely limits your visibility, especially when changing lanes or merging. We strongly advise against driving with a damaged mirror for safety reasons.

What’s the difference between OEM and aftermarket mirrors?

OEM (Original Equipment Manufacturer) mirrors are identical to the one that came with your car from the factory. They offer a guaranteed perfect fit, finish, and function. Aftermarket mirrors are produced by other companies. They are often more affordable but can vary in quality, fit, and the exact features offered. For a 2018 Honda Accord side mirror replacement, both can be viable, but OEM typically guarantees peace of mind.

You’ve made it! Replacing a side mirror on your 2018 Honda Accord might seem intimidating at first, but as you’ve seen, it’s a straightforward process that yields significant savings and a great sense of accomplishment. By following this guide, you’ve not only restored a crucial safety feature to your vehicle but also expanded your DIY skillset.

Remember, attention to detail, the right tools, and a bit of patience are your best friends in any automotive project. Keep those mirrors clean, adjusted, and functioning perfectly to ensure you always have a clear view of the road ahead and behind. Stay safe out there, and happy wrenching from your friends at FatBoysOffroad!
