The light is typically a straightforward swap: remove the license plate to access the bulb, replace it with a like-for-like bulb, and reattach. If your model uses an LED unit, you may need to replace the entire light housing rather than a single bulb.
This guide walks you through locating the light, gathering the right tools, safely removing the plate and bulb, selecting the correct replacement, and testing the circuit before you finish.
Tools and Materials
Before you start, gather the items you’ll need so you can complete the swap efficiently.
- A replacement bulb compatible with the license plate light (often a 194 or 168 wedge type; check the old bulb or owner's manual to confirm).
- Flat-head or Phillips screwdriver for the license plate screws (or a Torx driver if your screws require it).
- Gloves or a clean cloth to handle the new bulb and avoid transferring oils from your skin.
- A small flashlight to illuminate the housing, if needed.
- Optional: the appropriate replacement lighting unit if your Jeep uses an LED license plate light module.
With the right tools and bulb type on hand, you can perform the replacement in about 10–15 minutes.
Step-by-Step Instructions
Follow these steps in order to remove the old bulb and install the new one. If your unit is LED, the process may differ slightly, and you might replace the entire module rather than a single bulb.
- Remove the license plate to access the light housing. Use the proper screwdriver to take out the two screws that secure the plate, then carefully set the plate aside.
- Expose the license plate light housing. Look behind the plate area to locate the small bulb socket or assembly.
- Remove the bulb socket or bulb. If the bulb is a wedge/socket type, twist the socket counterclockwise to release it or unplug the connector if it is a plug-in style.
- Install the new bulb. Insert the new bulb into the socket with the correct orientation. If you’re replacing a plug-in module, reconnect the wiring harness as required. Avoid touching the glass portion of a halogen bulb with bare skin.
- Reassemble the light and plate. Reinsert the bulb/socket into the housing, then reattach the license plate with its screws.
- Test the light. Turn on your headlights or taillights to confirm the license plate light illuminates properly. If it does not, recheck the bulb seating, wiring, and fuses.
If the light still does not work after replacement, double-check the fuse and the wiring. Consult the owner's manual for the exact fuse location and amperage, and consider seeking a dealer or mechanic if the module itself is faulty (in the case of LED assemblies).
Bulb Type and Housing Specifics
Notes specific to the 2014 Grand Cherokee: the license plate light housing is typically mounted near the plate area on the rear of the vehicle. Most older bulbs are 194 or 168 wedge types, but some trims use LED modules. If you remove the bulb and see a glass bulb with a wedge base, buy a 12V replacement of the same type. If you encounter an LED module, you’ll generally replace the entire light unit rather than a single bulb.
Summary
Replacing the license plate light on a 2014 Jeep Grand Cherokee is a quick DIY task: remove the license plate, access and replace the bulb (or the entire LED housing if required), then reattach the plate and test the result. Always verify the exact bulb type before buying a replacement, and consult the owner’s manual or a parts diagram if you’re unsure. If problems persist after replacement, check fuses and wiring or seek professional assistance.
