2017 Nissan Altima Passenger Side Mirror

So, your 2017 Nissan Altima's passenger side mirror is giving you trouble? You're not alone. Whether it's cracked glass, a broken housing, a malfunctioning turn signal, or a motor that's given up the ghost, a damaged side mirror can be a real headache. It's not just about aesthetics; it's a safety issue. A functional side mirror is crucial for safe driving. Let's dive into some common problems and explore the solutions.

Common 2017 Altima Passenger Side Mirror Issues

First, let's identify what's likely causing your mirror woes. The 2017 Altima, like many modern vehicles, has a fairly complex side mirror assembly. Here are some frequent culprits:

Cracked or Broken Mirror Glass: This is probably the most common issue. A stray rock, a close encounter with a garbage can, or even just age can lead to cracks.
Damaged Mirror Housing: The plastic housing protects the inner workings of the mirror. Impacts, even minor ones, can crack or break the housing.
Malfunctioning Turn Signal: Many 2017 Altimas have integrated turn signals in the side mirrors. These can fail due to bulb burnout, wiring issues, or damage to the signal lens.
Power Mirror Issues: If your mirror won't adjust electrically, the motor, wiring, or switch could be the problem. Sometimes, it's just a blown fuse.
Folding Mirror Problems (if equipped): Some Altimas have power folding mirrors. If these aren't folding or unfolding correctly, the motor, gears, or control module may be at fault.
Vibration or Looseness: Over time, the mirror assembly can become loose, causing vibration at highway speeds. This is often due to worn or broken mounting hardware.

Diagnosing the Problem

Before you start ordering parts, it's essential to pinpoint the exact cause of the issue. Here's a simple diagnostic approach:

Visual Inspection: Carefully examine the mirror glass, housing, and mounting points for any visible damage, cracks, or loose connections.
Test the Functions: Try adjusting the mirror using the power controls (if equipped). Listen for motor noise. If the motor is running but the mirror isn't moving, the gears inside might be stripped.
Check the Turn Signal: Activate the turn signal and see if the mirror-mounted indicator is working. If not, check the bulb first.
Fuse Check: Consult your owner's manual to locate the fuse for the side mirrors. A blown fuse is an easy fix. Remember to replace it with the correct amperage fuse.
Wiring Inspection: Look for any damaged or disconnected wires near the mirror assembly. This might require removing the interior door panel (more on that later).

Solutions: Repair or Replacement?

Once you've identified the problem, you have two main options: repair or replace the entire mirror assembly. Here's a breakdown:

Repair

Repairing the mirror is often the more cost-effective option, especially for minor damage. Here are some common repair scenarios:

Replacing Cracked Mirror Glass: You can purchase replacement mirror glass online or at auto parts stores. These usually come with adhesive backing for easy installation. Be careful when removing the old glass to avoid cuts. Wear gloves!
Patching Minor Housing Cracks: Small cracks in the plastic housing can sometimes be repaired with epoxy or plastic repair kits. This is a temporary fix and may not look perfect, but it can extend the life of the mirror.
Replacing a Turn Signal Bulb: This is a simple DIY task. Consult your owner's manual for the correct bulb type and replacement procedure.
Tightening Loose Mounts: Sometimes, all it takes is tightening a few screws to eliminate vibration. Accessing these screws may require removing the interior door panel.

Tools Needed for Repairs:

Safety Glasses
Gloves
Screwdrivers (Phillips and Flathead)
Pliers
Socket Set
Trim Removal Tools (optional, but highly recommended to avoid damaging interior trim)
Adhesive (for mirror glass replacement)
Epoxy or Plastic Repair Kit (for housing cracks)

Replacement

If the damage is extensive, or if the internal mechanisms are faulty, replacing the entire mirror assembly is often the best solution.

Complete Mirror Assembly Replacement: This involves removing the old mirror and installing a new one. This is usually a straightforward process, but it does require some mechanical skill.

Steps for Replacing the Entire Mirror Assembly:

Gather Your Tools: You'll need the tools listed above, plus a replacement mirror assembly. Make sure you order the correct part for your vehicle's year, make, and model, and with the correct features (power, heated, turn signal, etc.).
Disconnect the Battery (Important!): This prevents accidental electrical shorts during the replacement process.
Remove the Interior Door Panel: This is necessary to access the mirror mounting bolts and wiring connector. Use trim removal tools to carefully pry the panel away from the door. There are usually screws hidden behind plastic covers.
Disconnect the Wiring Harness: Unplug the electrical connector from the mirror assembly. There's usually a clip that needs to be released.
Remove the Mounting Bolts: Use a socket wrench to remove the bolts that secure the mirror to the door.
Remove the Old Mirror: Carefully pull the old mirror assembly away from the door.
Install the New Mirror: Align the new mirror assembly with the mounting holes and secure it with the bolts.
Connect the Wiring Harness: Plug the electrical connector into the new mirror assembly.
Reinstall the Interior Door Panel: Align the panel with the door and snap it back into place. Reinstall any screws.
Reconnect the Battery:
Test the Mirror: Make sure the power functions (adjustment, turn signal, folding, heated, etc.) are working correctly.

Where to Buy Replacement Mirrors:

Auto Parts Stores: NAPA, AutoZone, Advance Auto Parts, O'Reilly Auto Parts
Online Retailers: Amazon, eBay, RockAuto
Nissan Dealership: This is usually the most expensive option, but you can be sure you're getting the correct part.

Cost Considerations

The cost of repairing or replacing your 2017 Altima's passenger side mirror can vary depending on several factors:

Type of Damage: Replacing just the mirror glass is much cheaper than replacing the entire assembly.
Mirror Features: Mirrors with power adjustment, heated glass, turn signals, and power folding features are more expensive.
Part Source: Aftermarket parts are usually cheaper than OEM (Original Equipment Manufacturer) parts.
Labor Costs: If you choose to have a mechanic do the work, you'll need to factor in labor costs.

Approximate Costs:

Replacement Mirror Glass: $20 - $50
Aftermarket Mirror Assembly (without features): $50 - $100
Aftermarket Mirror Assembly (with power and turn signal): $100 - $200
OEM Mirror Assembly (from Nissan): $200 - $400+
Professional Installation: $50 - $150 (depending on the shop and the complexity of the job)

Preventative Maintenance

While accidents happen, there are a few things you can do to prolong the life of your side mirrors:

Be Careful When Parking: Pay attention to your surroundings when parking to avoid bumping into other vehicles or objects.
Fold Mirrors in Tight Spaces (if equipped): If your Altima has power folding mirrors, use them when parking in tight spots to prevent damage.
Clean Your Mirrors Regularly: Use a mild glass cleaner and a soft cloth to keep your mirrors clean and clear.
Inspect Regularly: Periodically check your mirrors for any signs of damage or looseness. Addressing small problems early can prevent them from becoming bigger problems later.

When to Seek Professional Help

While many mirror repairs are DIY-friendly, there are times when it's best to consult a professional:

If You're Uncomfortable Working on Your Car: If you're not confident in your mechanical skills, it's always better to leave the work to a qualified mechanic.
If the Wiring is Damaged: Electrical problems can be tricky to diagnose and repair. A professional can properly troubleshoot the wiring and ensure that everything is working correctly.
If You're Dealing with Airbag-Related Components: Some side mirrors are located near airbag sensors. If you're working in this area, it's crucial to disconnect the battery and take extra precautions to avoid accidentally deploying the airbag. It's often best to leave this type of work to a professional.

By following these steps, you can diagnose and address common passenger side mirror problems on your 2017 Nissan Altima. Remember safety first, and don't hesitate to seek professional help if you're unsure about anything. Good luck, and safe driving!
