How To Open Nissan Altima Trunk From The Inside

So, you're stuck inside your Nissan Altima and the trunk won't open? Don't worry, it happens! This article will walk you through the common reasons why your Altima's trunk release might fail from the inside and, more importantly, how to get it open. Getting your trunk open isn't just about convenience; it could be crucial in an emergency where you need quick access to items inside, like a spare tire, jumper cables, or even safety equipment. Knowing how to troubleshoot and fix this issue yourself can save you time and money.

Symptoms of a Trunk Release Failure

Before diving into fixes, let's make sure we're dealing with the right problem. Here are some common signs that your Nissan Altima's trunk release system isn't working as it should:

The trunk release button on the driver's side dash isn't responding. You press it, but nothing happens. No click, no trunk opening, just silence.
The key fob trunk release button is also unresponsive. This helps you rule out the dash switch as the sole problem.
You hear a faint clicking sound coming from the trunk area when you press the release button, but the trunk latch doesn't disengage. This suggests the solenoid is getting power but failing to operate correctly.
The emergency trunk release lever inside the trunk isn't working. This is a critical safety feature, and if it fails, it's a major concern.
The trunk opens intermittently. Sometimes it works, sometimes it doesn't, suggesting a loose connection or a failing component.
The trunk light isn't turning on when the trunk is manually opened (if you can manage to open it manually). This *could* indicate a broader electrical issue, but isn't always related directly to the release mechanism.

Root Causes of Trunk Release Problems

Several factors can cause your Altima's trunk release to fail. Here’s a breakdown of the most common culprits:

Faulty Trunk Release Solenoid: This is often the prime suspect. The solenoid is an electromagnet that, when energized by the release button, pulls a lever to unlatch the trunk. Over time, the solenoid can weaken, burn out, or become mechanically stuck. This is especially common in older Altimas.
Damaged or Broken Wiring: Wires running between the car's body and the trunk lid can become frayed or broken due to repeated opening and closing. This can interrupt the electrical signal to the solenoid. Look for damage in the rubber boot that protects the wiring harness near the trunk hinges.
Blown Fuse: A blown fuse in the trunk release circuit is a simple but common cause. Fuses are designed to protect the electrical system, and a surge or short circuit can cause them to blow, cutting power to the solenoid.
Defective Trunk Release Switch: The switch on the dashboard or the key fob transmitter itself could be faulty. Although less common than a solenoid failure, these switches can wear out or become damaged.
Sticking Trunk Latch Mechanism: The latch itself could be sticking or corroded, preventing the solenoid from releasing it even if the solenoid is working. This is more likely to occur in areas with high humidity or where the car is exposed to harsh weather conditions.
Actuator Failure: In some Altima models, the trunk release uses an actuator motor instead of a solenoid. These actuators can fail similarly to solenoids, either mechanically or electrically.
Body Control Module (BCM) Issue: While less likely than the above issues, a malfunctioning BCM can sometimes cause problems with the trunk release. The BCM controls various electrical functions in the car, including the trunk release.

What Happens if You Ignore the Problem?

Ignoring a malfunctioning trunk release can lead to several frustrating and potentially dangerous situations:

Inability to Access the Trunk: This is the most obvious consequence. You won't be able to easily access items in your trunk, which can be inconvenient for everyday tasks like grocery shopping, transporting luggage, or accessing emergency equipment.
Emergency Situation Hazards: If you have a flat tire or need to access your spare tire and tools in an emergency, a stuck trunk can delay repairs and create a dangerous situation, especially if you're on the side of a busy road. Similarly, inability to access a first-aid kit could have serious consequences.
Security Concerns: If the trunk is stuck closed but not properly latched, it *could* potentially pop open unexpectedly while driving, especially on bumpy roads. This could result in loss of cargo.
Further Damage: Continuously trying to force the trunk open with a faulty mechanism could potentially damage the latch, solenoid, or wiring, leading to more costly repairs down the line.

Recommended Fixes

Here's a step-by-step guide to troubleshooting and fixing your Nissan Altima's trunk release problem:

Check the Fuse: Locate the fuse box (usually under the dashboard or in the engine compartment). Consult your owner's manual to identify the fuse for the trunk release or power door locks (they are often on the same circuit). Use a fuse tester or simply visually inspect the fuse for a broken filament. If the fuse is blown, replace it with a new fuse of the same amperage. If the new fuse blows immediately, there's likely a short circuit in the wiring.
Test the Trunk Release Switch: Using a multimeter, check for continuity at the trunk release switch on the dashboard when the button is pressed. If there's no continuity, the switch may be faulty and need replacement. A replacement switch is typically inexpensive and can be installed with basic tools.
Inspect the Wiring Harness: Carefully inspect the wiring harness that runs from the car's body to the trunk lid, especially in the area where the harness flexes as the trunk opens and closes. Look for frayed, cracked, or broken wires. If you find any damaged wires, repair them using electrical tape or wire connectors. For more extensive damage, you may need to replace the entire wiring harness section.
Test the Trunk Release Solenoid/Actuator:
1. Access the Solenoid/Actuator: This usually involves removing the trunk lining or trim panel. Consult your Altima's repair manual or online resources for specific instructions for your model year.
2. Test for Voltage: Use a multimeter to check if the solenoid/actuator is receiving voltage when the trunk release button is pressed. If there's no voltage, the problem lies in the wiring or the switch.
3. Direct Power Test: If voltage is present, try applying direct power to the solenoid/actuator (using a jumper wire connected to the car's battery). If the solenoid/actuator activates and releases the trunk latch, the solenoid/actuator itself is likely working, and the problem may be a weak electrical signal.
4. Solenoid/Actuator Replacement: If the solenoid/actuator doesn't activate with direct power, it needs to be replaced. Replacement solenoids/actuators are readily available at auto parts stores.
Check the Trunk Latch Mechanism: Inspect the trunk latch mechanism for corrosion, dirt, or obstructions. Clean the latch with a lubricant like WD-40 and try manually operating it. If the latch is sticking, you may need to disassemble it, clean it thoroughly, and lubricate it. If the latch is severely damaged or corroded, it may need to be replaced.
Use the Emergency Trunk Release: Locate the emergency trunk release lever inside the trunk. It's usually a glow-in-the-dark handle. Pull the lever firmly to release the trunk latch. If this doesn't work, the cable connecting the lever to the latch may be broken or disconnected. This requires further investigation and may involve removing the trunk lining to access the mechanism.
