Hey guys, so your Infiniti i35 trunk release isn't working? Don't sweat it! This is a super common issue, and thankfully, it's often something you can tackle yourself without a trip to the mechanic. We're going to dive deep into why this might be happening and walk you through the most likely culprits. Think of this as your go-to guide for getting that trunk popped open again. We'll cover everything from simple fixes to slightly more involved troubleshooting, so stick around!

Why Isn't My Infiniti i35 Trunk Opening?

Alright, let's get down to the nitty-gritty. When your Infiniti i35 trunk release isn't working, there are several potential reasons. The most frequent offenders usually involve the electrical system. Your trunk release is an electronic mechanism, meaning it relies on power, switches, and wiring to function. If any part of that circuit is broken, interrupted, or just plain dead, you're going to be left with a stubbornly shut trunk. We're talking about things like blown fuses, faulty switches (both the one inside the car and potentially the one on the trunk lid itself), or even a problem with the actuator motor that actually does the work of unlatching the trunk. Sometimes, it can be as simple as a dead battery in your key fob, if you're relying on that for remote access. Other times, it might be a more complex wiring issue, perhaps a frayed wire or a loose connection somewhere in the car's harness. It's also worth considering if there's any physical obstruction jamming the latch mechanism itself. While less common for an electronic failure, it's still a possibility, especially if you recently loaded something bulky or unusual into the trunk. We'll explore each of these possibilities in detail to help you pinpoint the exact cause of your particular trunk trouble.

Troubleshooting the Trunk Release System

Okay, so you've confirmed your Infiniti i35 trunk release isn't working, and you're ready to roll up your sleeves. The first thing we always want to check is the fuse. Seriously, guys, this is the easiest fix and often overlooked. Your i35 has a fuse box, usually located under the dashboard on the driver's side or sometimes in the engine compartment. You'll need to consult your owner's manual (or do a quick online search for your specific model year) to find the exact location of the fuse that controls the trunk release. Once you've located it, pull out the fuse and inspect it. If the metal filament inside is broken, it's blown, and you'll need to replace it with a new one of the exact same amperage. Don't go putting in a higher amperage fuse, as that can cause electrical damage! If the fuse looks good, the next step is to check the switches. Your i35 typically has a trunk release button inside the cabin, often on the driver's side door panel or near the steering column. Try pressing it firmly and see if you hear any click or response. If that switch seems dead, it might be the culprit. You can also try the remote key fob. Make sure the battery in your fob is fresh. Sometimes, a weak battery won't send a strong enough signal. If both the interior switch and the key fob aren't doing the trick, it's time to look at the trunk lid switch itself. This is the button located on the exterior of the trunk lid. It can get dirty, corroded, or simply fail over time. You might be able to clean it with some electrical contact cleaner, but if it's physically damaged, it will likely need replacement. Don't forget to check the wiring. This is where things can get a bit more involved. Look for any visible signs of damage to the wires leading to the trunk latch mechanism. This often requires removing some interior trim panels. If you're not comfortable with this, it might be time to consult a professional. Remember, we're trying to get that trunk open, so let's systematically go through these steps!

Checking the Fuse Box

Let's get specific about the fuse box, because honestly, this is where a ton of Infiniti i35 trunk release not working issues get solved. First off, you need to locate it. For most Infiniti i35 models, you'll find a fuse box tucked away under the dashboard, typically on the driver's side, near the steering column. Sometimes, there's a small panel or cover you'll need to pop off. If you're unsure, your owner's manual is your best friend here – it'll have diagrams showing you exactly where it is and what each fuse controls. Once you've found the fuse box, you're looking for a specific fuse labeled for the trunk, trunk opener, or a similar designation. It'll be a small plastic block with metal prongs and a tiny filament inside. You'll want to use a fuse puller (often found in the fuse box itself or easily bought at an auto parts store) to gently remove the suspect fuse. Now, hold it up to the light. If that little metal wire inside is broken or looks burnt, bingo! That's your problem. You'll need to replace it with a new fuse that has the exact same amperage rating. You'll see a number on top of the fuse; make sure the new one matches it perfectly. Using a fuse with a higher rating is a big no-no and can cause electrical fires or damage other components. Pop the new fuse in, and then try your trunk release again. If the new fuse blows immediately, you've likely got a short circuit somewhere, which is a bit more serious and might require professional help. But if the fuse was the issue, you're golden!

Inspecting the Switches

Beyond the fuse, the switches are the next logical point of failure when your Infiniti i35 trunk release isn't working. Think about it – these are the buttons you interact with. We've got a few main suspects here. First, there's the interior release button. This is usually located on the driver's side door panel or sometimes down near the steering wheel. Give it a good, firm press. Do you hear any faint click from the rear of the car? Even a tiny sound can indicate the switch is at least sending a signal. If you get absolutely nothing, the switch itself might be faulty or have a bad connection behind it. Second, if you're using your key fob, try replacing the battery. It's amazing how often a weak fob battery can cause intermittent issues or complete failure. Pop in a fresh coin cell battery (usually a CR2032), and give it another shot. Sometimes, the fob just needs to be re-synchronized with the car, but that's a less common scenario for a simple failure. Finally, and this is crucial, there's the exterior trunk release button on the trunk lid itself. This little guy takes a beating from the elements. It can get clogged with dirt, grime, or road salt, leading to poor contact. Sometimes, a gentle cleaning with a spray of electrical contact cleaner (make sure the car is off!) can work wonders. If cleaning doesn't help, or if the button feels physically stuck or broken, it's very likely the switch has failed and will need to be replaced. Testing these switches usually involves checking for continuity with a multimeter, but for most DIYers, visual inspection, cleaning, and battery replacement are the first steps before considering deeper diagnostics.

Examining the Key Fob and Battery

Let's talk about the key fob specifically, because a dead or dying battery in your key fob is a super common reason why your Infiniti i35 trunk release isn't working remotely. If you primarily use the button on the fob to pop your trunk, and suddenly it's not responding, don't jump to conclusions about major electrical failures just yet. The first, simplest, and cheapest thing to do is replace the battery. Most Infiniti key fobs use a standard coin cell battery, typically a CR2032. You can usually find these at any grocery store, convenience store, or pharmacy. You'll need to carefully pry open the key fob – check online for a video specific to your i35 fob model, as the process can vary slightly. Make sure you note the orientation of the old battery before you remove it, and insert the new one the same way. Once the new battery is in, put the fob back together and try the trunk release button again. If it works now, great! You just saved yourself time and money. If it still doesn't work, the battery might not have been the issue, or perhaps the fob itself has an internal problem. It's also worth noting that sometimes, especially after a battery change or if the fob has been dropped, the fob can lose its programming and need to be re-synchronized with the car. This usually involves a specific sequence of button presses or turning the ignition on and off, and again, your owner's manual or an online resource should guide you through this process. But before you go down that rabbit hole, always try a fresh battery first!

Investigating the Trunk Latch Actuator

If you've gone through the fuses, switches, and key fob battery, and your Infiniti i35 trunk release still isn't working, it's time to look at the trunk latch actuator. This is the mechanical component, usually an electric motor, that actually physically unlatches your trunk lid when it receives the signal from the switch or fob. Over time, these actuators can wear out, seize up, or the internal motor can fail. Diagnosing a bad actuator can be a bit tricky. Sometimes, you might hear a faint clicking sound from the trunk area when you try to activate the release, but the latch doesn't open. This could indicate the motor is trying to work but is jammed or too weak. Other times, you'll hear absolutely nothing, suggesting the motor isn't getting power or has completely died. Accessing the actuator typically involves removing the interior trim panel on the inside of the trunk lid. This can be a bit of a puzzle, as there are usually clips and fasteners holding it in place. Once you have access, you can sometimes try to manually manipulate the latch mechanism to see if it's physically stuck. You can also check for power going to the actuator using a multimeter if you're comfortable with that. If the actuator is indeed the problem, it will need to be replaced. This is often a job that requires a bit more mechanical skill, and if you're not comfortable removing trim panels or dealing with wiring, it might be best to have a mechanic handle this part. But knowing that the actuator is a strong possibility helps you decide your next steps.

Electrical Connections and Wiring

Now, let's talk about the hidden heroes (and sometimes villains) of your Infiniti i35 trunk release not working: the electrical connections and wiring. These are the pathways that carry the signal and power from your switches and fob to the trunk latch actuator. Over time, wires can become frayed, insulation can crack, or connectors can corrode, especially in areas exposed to moisture or constant flexing, like near the trunk hinge. If you've decided to remove the interior trunk trim panel to get a better look, this is where you'll want to focus your attention. Carefully inspect all the wiring harnesses connected to the trunk latch mechanism and the actuator. Look for any signs of physical damage – cuts, abrasions, or melted insulation. Pay close attention to the connectors; make sure they are clean, free of corrosion, and firmly seated. Sometimes, a connector might just be loose, and a firm push can resolve the issue. If you find a damaged wire, you might be able to repair it with a soldering iron and some heat-shrink tubing, but this requires some electrical know-how. A loose connection is often easier to fix – just ensure it's plugged in securely. If you're comfortable using a multimeter, you can check for continuity in the wires and test if voltage is reaching the actuator when the release button is pressed. This helps isolate whether the problem is in the wiring itself or further down the line at the actuator. Remember to disconnect the car battery before probing any electrical components to avoid short circuits or shocks. Faulty wiring can be a frustrating gremlin to track down, but it's a crucial step in the troubleshooting process.

Manual Trunk Release (If Applicable)

Sometimes, especially if the Infiniti i35 trunk release isn't working due to a complete electrical failure (like a dead actuator or wiring issue), you might be looking for a way to manually get that trunk open. Many cars have a hidden manual release mechanism, though it's not always guaranteed or easily accessible. For the Infiniti i35, there isn't typically an easily accessible manual cable pull like you might find in some other vehicles. However, in some dire situations, you might be able to access the latch mechanism from the inside of the trunk. This usually involves climbing into the trunk (if possible and safe) and removing the interior trim panel from the lid. Once you can see the latch assembly, you might be able to use a screwdriver or a similar tool to manually push or pull the release lever. This is often a last resort and can be difficult or even impossible depending on the specific setup and how jammed the mechanism is. It's also important to note that if the trunk is completely sealed shut and you cannot access the interior, manual release from the outside is generally not an option without potentially damaging the trunk lid. If you're in this situation, calling a locksmith or a roadside assistance service specializing in vehicle entry might be your best bet. They have tools and techniques to open trunks without causing significant damage. Always prioritize safety and avoid forcing anything that could cause more harm to your vehicle.

When to Call a Professional

Alright guys, we've covered a lot of ground trying to get your Infiniti i35 trunk release working again. You've checked the fuses, tinkered with the switches, maybe even replaced a key fob battery. But sometimes, despite your best efforts, the problem is just beyond a simple DIY fix. If you've gone through all the troubleshooting steps and the trunk is still stubbornly shut, it's probably time to wave the white flag and call in the pros. This is especially true if you suspect a faulty trunk latch actuator or a complex wiring issue. These problems often require specialized tools, like diagnostic scanners that can read error codes from your car's computer, or precise knowledge of the vehicle's electrical system. Attempting repairs on these components without the right expertise can sometimes lead to more damage, costing you more in the long run. Furthermore, if you're not comfortable removing interior trim panels or working with electrical wiring, it's always safer to let a qualified mechanic handle it.
