2015 Nissan Altima Driver Side Mirror

Having trouble with the driver's side mirror on your 2015 Nissan Altima? You're not alone. It's a common issue, and thankfully, most problems are manageable with a little know-how. This article will walk you through common issues, troubleshooting steps, and possible solutions, from a simple mirror replacement to a more involved motor repair.

Common 2015 Altima Driver's Side Mirror Problems

Before we dive into fixes, let's identify the most frequent issues Altima owners face with their driver's side mirrors:

Cracked or Broken Mirror Glass: This is often caused by accidental bumps, road debris, or even temperature fluctuations.
Malfunctioning Power Adjustment: The mirror doesn't adjust horizontally or vertically when using the interior controls.
Broken Mirror Housing: The plastic casing surrounding the mirror is cracked or damaged, often from an impact.
Loose or Wobbly Mirror: The entire mirror assembly feels unstable and vibrates while driving.
Non-Functional Turn Signal (if equipped): The integrated turn signal in the mirror doesn't illuminate.
Wiring Issues: This can manifest as any of the above problems, especially with power adjustment or turn signals.

Troubleshooting Your Altima's Driver's Side Mirror

The key to a successful repair is accurate diagnosis. Here's a step-by-step approach to figuring out what's wrong:

1. Visual Inspection

Start with a thorough visual check. Look for:

Obvious cracks, breaks, or missing pieces in the mirror glass or housing.
Loose connections or wires dangling near the mirror.
Signs of impact damage.

2. Power Adjustment Test

Turn the ignition to the "ON" position (engine doesn't need to be running). Use the interior mirror adjustment controls to try moving the mirror in all directions. Note:

Does the mirror respond at all? If not, check the fuse for the power mirrors. The fuse location is usually indicated in your owner's manual or on a diagram inside the fuse box cover (typically located under the dashboard or in the engine compartment).

If the fuse is blown, replace it with a new one of the correct amperage. If the new fuse blows immediately, there's likely a short circuit in the wiring or the mirror motor itself.

Important: Never use a fuse with a higher amperage than specified. This can damage your car's electrical system and potentially cause a fire.

If the mirror moves in some directions but not others, the motor might be failing, or there could be a mechanical issue within the mirror assembly.

3. Turn Signal Check (if equipped)

With the ignition "ON," activate the turn signal on the driver's side. Observe the mirror turn signal. If it doesn't light up:

Check the bulb. On some models, you can access the bulb by carefully prying off the turn signal lens. Replacement bulbs are inexpensive.
Inspect the wiring harness that connects to the mirror. Look for damaged or frayed wires.

4. Wobbly Mirror Assessment

Gently try to move the entire mirror assembly. If it feels excessively loose, the mounting bolts or screws may be loose. On some Altimas, these are accessible by carefully removing a small plastic cover on the inside of the door, near the mirror mount. Tightening these fasteners might solve the problem. If the mounting is broken internally, the entire assembly likely needs replacement.

Repair Options and Solutions

Once you've identified the problem, you can explore these solutions:

1. Replacing the Mirror Glass

A cracked or broken mirror glass is the easiest fix. You can purchase replacement mirror glass online or at auto parts stores. The cost typically ranges from $20 to $50. Here's the general procedure:

Safety First: Wear gloves to protect your hands from sharp glass edges.
Remove the Old Mirror: Carefully pry out the broken glass. You might need to use a plastic trim removal tool to avoid damaging the mirror housing. Use a heat gun or hairdryer to gently warm the adhesive if the glass is stubbornly stuck.
Clean the Surface: Remove any remaining adhesive from the mirror housing using a cleaner specifically designed for automotive surfaces.
Install the New Mirror: Many replacement mirrors come with adhesive backing. Simply peel off the protective layer and press the new mirror firmly into place.

2. Replacing the Entire Mirror Assembly

If the mirror housing is damaged, the motor is malfunctioning, or the turn signal is beyond repair, replacing the entire assembly is often the best option. New aftermarket mirror assemblies range from $50 to $200, depending on features (power adjustment, heated mirror, turn signal, etc.). OEM (Original Equipment Manufacturer) mirrors will generally be more expensive.

Here's a simplified overview of the replacement process:

Gather Your Tools: You'll typically need a Phillips head screwdriver, a flathead screwdriver or trim removal tool, and potentially a socket set.
Remove the Interior Door Panel: This usually involves removing screws hidden behind plastic covers and then carefully prying the panel away from the door. There are numerous online tutorials specific to the 2015 Altima that demonstrate this.
Disconnect the Wiring Harness: Disconnect the electrical connector(s) that supply power to the mirror. Be gentle and note the orientation of the connector.
Remove the Old Mirror: Unbolt the mirror assembly from the door.
Install the New Mirror: Bolt the new mirror assembly to the door.
Connect the Wiring Harness: Connect the electrical connector(s) to the new mirror.
Test the Mirror: Turn the ignition "ON" and test the power adjustment, heated mirror (if equipped), and turn signal.
Reinstall the Door Panel: Carefully reinstall the interior door panel.

Pro Tip: Before completely reassembling the door panel, test all the door's electrical functions (window, door lock, etc.) to ensure you haven't accidentally disconnected anything.

3. Wiring Repair

If you suspect a wiring issue, carefully inspect the wiring harness that connects to the mirror. Look for:

Cut, frayed, or exposed wires.
Corroded connectors.
Loose connections.

If you find damaged wires, you can try to repair them using butt connectors and electrical tape. However, if the damage is extensive, it's often best to replace the entire wiring harness, which can be purchased from an auto parts store or online. Be extremely careful when working with electrical components.

Important: Disconnect the negative terminal of your car battery before working on any electrical components to prevent accidental shorts and shocks.

4. Professional Repair

If you're not comfortable performing the repairs yourself, or if you're dealing with complex electrical issues, it's always best to take your Altima to a qualified mechanic. A professional can accurately diagnose the problem and perform the necessary repairs safely and effectively. Labor costs for mirror replacement can range from $80 to $200, depending on the complexity of the job.

Approximate Costs

Here's a summary of estimated costs:

Replacement Mirror Glass: $20 - $50
Aftermarket Mirror Assembly: $50 - $200
OEM Mirror Assembly: $150 - $350+
Wiring Harness: $20 - $80
Professional Labor: $80 - $200+
