Why Your 2019 Jeep Cherokee Tail Light Needs Immediate Attention
A functioning tail light isn’t just about avoiding a ticket; it’s fundamental to your safety and the safety of others on the road or trail. Your rear illumination system signals your presence, braking, and turning intentions.
Ignoring a broken or dim tail light can lead to serious consequences. Reduced visibility significantly increases the risk of rear-end collisions, especially in low-light conditions, heavy rain, or fog. It’s a critical component for safe operation.
Common Causes of Tail Light Failure
Several factors can lead to your Jeep Cherokee’s tail lights going out. Understanding these helps in diagnosing the problem quickly.
- Burned-Out Bulb: This is the most frequent culprit. Filaments inside incandescent bulbs simply break over time.
- Damaged Wiring: Corrosion, chafing, or impact can compromise the electrical connection to the tail light assembly.
- Blown Fuse: A short circuit or electrical overload can trip a fuse, cutting power to the lights.
- Cracked Lens/Housing: Accidents, flying debris, or even minor impacts can damage the outer lens, allowing water ingress and damaging internal components.
- Faulty Tail Light Assembly: Less common, but sometimes the entire assembly, including bulb sockets or internal circuitry, can fail.
Before you begin any work, a quick visual inspection can often pinpoint the issue. Check both sides of the vehicle to see if it’s an isolated problem or a broader electrical issue.
Gathering Your Gear: Essential Tools for a 2019 Jeep Cherokee Tail Light Replacement
Preparation is key to any successful DIY project. Having the right tools on hand will make the 2019 Jeep Cherokee tail light replacement process smooth and frustration-free.
You won’t need a full mechanic’s garage for this task, but a few specific items are crucial. Gather everything before you start to avoid interruptions.
Must-Have Tools and Materials

Step-by-Step Guide: How to Perform a 2019 Jeep Cherokee Tail Light Replacement
Now that you’re prepped and safe, let’s dive into the core task. This section will walk you through replacing the tail light assembly or bulb on your 2019 Jeep Cherokee.
Follow these steps carefully, and you’ll have your rear lights shining brightly in no time. We’ll assume you’re replacing the entire assembly, which includes bulb replacement.
1. Accessing the Tail Light Assembly
The tail light assembly on a 2019 Jeep Cherokee is typically secured by a few bolts and clips, and often requires removing some interior trim to access fully.
Open your rear liftgate. On the inside of the liftgate opening, near the tail light you’re working on, you’ll see a few screws or bolts that hold the tail light assembly in place.
- Locate the access panel or trim piece on the inside of the cargo area, adjacent to the tail light. You might need to gently pry this open with your plastic trim removal tool.
- Once exposed, you’ll usually find two or three bolts (often Torx or small metric hex bolts) securing the tail light assembly to the vehicle body. Remove these bolts using your socket wrench and appropriate bit.
- Carefully inspect for any hidden clips or additional fasteners. Some models might have a single plastic retainer that needs to be gently pried.
2. Removing the Old Tail Light
With the fasteners removed, the tail light assembly should now be loose. Exercise caution to avoid scratching your paint.
Gently pull the tail light assembly straight out from the vehicle body. It might be snug due to weather stripping or alignment pins.
- Apply steady, even pressure. Wiggle it slightly if it’s stubborn, but never force it.
- Once the assembly is free from the body, you’ll see the wiring harness connected to the back.
- Carefully disconnect the electrical connector by pressing the release tab and pulling it apart. Inspect the connector for any signs of corrosion or damage.
3. Replacing the Bulb (If Applicable)
If you’re only replacing a burned-out bulb within a good assembly, this is where you’d perform that step.
Twist the bulb sockets counter-clockwise to remove them from the housing. Pull the old bulb straight out of its socket.
- Be careful not to touch the glass of the new bulb with your bare fingers, as oils can shorten its lifespan. Use a clean cloth or glove.
- Insert the new bulb firmly into the socket, then twist the socket back into the tail light housing until it locks.
4. Installing the New Tail Light Assembly
Now, it’s time to install your new or repaired tail light assembly.
First, connect the electrical wiring harness to the new tail light assembly. Ensure it clicks securely into place.
- Align the new tail light assembly with the mounting holes and alignment pins on the vehicle body.
- Gently push the assembly into place until it sits flush. Ensure the weather stripping creates a good seal.
- Reinstall the mounting bolts you removed earlier. Hand-tighten them first, then use your socket wrench to snug them down. Do not overtighten, as this can crack the plastic housing.
- Replace any interior trim panels or access covers you removed.
5. Testing Your New Tail Light
Before you button everything up and hit the road, always test your work.
Reconnect your battery’s negative terminal if you disconnected it. Turn on your Jeep’s ignition, but you don’t need to start the engine.
- Turn on your headlights and check that the tail lights illuminate.
- Have someone depress the brake pedal while you check the brake lights.
- Activate your turn signals (left and right) to ensure they flash correctly.
- Put the vehicle in reverse (with the parking brake engaged) and check the reverse lights.
If everything works as expected, congratulations! You’ve successfully completed your 2019 jeep cherokee tail light replacement.
Troubleshooting Common Issues During Tail Light Service
Even with careful planning, sometimes things don’t go perfectly. Here are a few common hiccups you might encounter and how to address them.
Don’t get discouraged if your lights don’t work immediately. Most issues are minor and easily fixable.
- Light Still Not Working: Double-check the bulb. Is it seated correctly? Is it the right type? Inspect the wiring harness for loose connections or corrosion. Check the fuse box for a blown fuse related to the tail lights.
- Flickering Light: This often indicates a loose connection or a partially corroded wire. Disconnect and reconnect the electrical connector, perhaps applying a small amount of dielectric grease.
- Cracked Plastic Trim: If a trim piece cracks during removal, assess if it’s cosmetic or structural. Many trim pieces can be replaced relatively cheaply, or in some cases, epoxied.
- Difficulty Removing Assembly: If the tail light is stuck, ensure all bolts and clips are truly removed. Sometimes, a gentle tap with a rubber mallet (protected by a cloth) can help break a stubborn seal.
For persistent electrical problems, especially if multiple lights are affected, it might be time to consult a professional mechanic. They have advanced diagnostic tools to pinpoint complex wiring issues.
Upgrading Your Jeep Cherokee Tail Lights: Beyond the Stock Bulb
Replacing a faulty tail light is a great opportunity to consider an upgrade. Enhancing your Jeep’s lighting can improve aesthetics and, more importantly, increase visibility and safety.
The aftermarket offers a range of options for the 2019 Jeep Cherokee. These can provide a modern look and superior performance.
Popular Tail Light Upgrade Options
- LED Bulb Conversion: If your Cherokee came with incandescent bulbs, you can often swap them out for brighter, more efficient LED bulbs. These draw less power, last longer, and illuminate faster. Ensure they are “CANBUS compatible” to avoid error messages.
- Aftermarket LED Tail Light Assemblies: Many manufacturers offer complete LED tail light assemblies designed specifically for the 2019 Cherokee. These often feature unique designs, sequential turn signals, and significantly brighter output.
- Smoked Lenses: For a more aggressive, customized look, some owners opt for smoked or tinted tail light lenses. Be mindful of local regulations, as excessively dark tints can reduce light output and be illegal.
When choosing an upgrade, always prioritize reputable brands. Quality aftermarket parts will ensure durability and proper fitment, crucial for off-road enthusiasts who demand rugged components.
Frequently Asked Questions About 2019 Jeep Cherokee Tail Light Replacement
We’ve covered a lot, but you might still have a few lingering questions. Here are answers to some common queries.
Do I need to replace the entire tail light assembly or just the bulb?
It depends on the damage. If only a bulb has burned out, you can usually just replace the bulb. However, if the lens is cracked, water has gotten inside, or the internal wiring/sockets are damaged, you’ll need to replace the entire tail light assembly.
How long does a 2019 Jeep Cherokee tail light replacement take for a DIYer?
For an average DIYer with the right tools, replacing a tail light assembly on a 2019 Jeep Cherokee typically takes about 30 minutes to an hour per side. Bulb replacement alone is often quicker, around 15-30 minutes.
Can I mix and match different types of bulbs (e.g., one LED, one incandescent)?
While technically possible, it’s not recommended. Different bulb types can have varying brightness and color temperatures, leading to an inconsistent appearance. For optimal performance and aesthetics, replace both bulbs or assemblies on the same axle with matching types.
What if my new tail light still doesn’t work after installation?
First, recheck all connections. Ensure the electrical connector is fully seated and the bulb (if applicable) is installed correctly. Then, check the fuse box for any blown fuses. If all looks good and it’s still not working, the new part itself might be faulty, or there could be a deeper electrical issue that warrants professional diagnosis.
Is a tail light replacement covered under warranty?
If your 2019 Jeep Cherokee is still under its factory bumper-to-bumper warranty, a tail light assembly failure due to a manufacturing defect might be covered. Normal wear and tear (like a burned-out bulb) or damage from an accident typically are not. Always check your specific warranty terms.
Conclusion: Light Up Your Path with Confidence
Replacing the tail light on your 2019 Jeep Cherokee is a rewarding and relatively simple DIY project that significantly impacts your safety and compliance. By following our detailed guide, you’ve not only saved yourself a trip to the mechanic but also gained valuable experience working on your rig.
