Changing the daytime running light (DRL) on a 2017 Jeep Cherokee might sound simple, but it’s a task that can leave many owners frustrated. The DRLs are a key safety feature, making your vehicle more visible during the day. If one stops working, it’s not just an aesthetic issue—it’s about safety and staying compliant with road regulations. Replacing the DRL yourself can save money and time, but only if you know the right process and avoid common mistakes.
Many people overlook important steps, such as choosing the correct bulb type or disconnecting the battery for safety. Others may damage the headlamp housing by forcing it open or skipping protective gloves.
In this guide, you’ll learn how to change the daytime running light on your 2017 Jeep Cherokee with confidence.
We’ll cover everything from tools and bulb selection to installation, troubleshooting, and a few practical tips that even experienced DIYers sometimes miss.
Understanding Daytime Running Lights On The 2017 Jeep Cherokee
The 2017 Jeep Cherokee uses separate bulbs for daytime running lights, which are not the same as the main headlights. The DRLs are designed to stay on whenever the engine is running, making your SUV more visible in daylight. These bulbs are housed within the headlamp assembly, and their location can make replacement tricky if you’re not prepared.
Most US 2017 Cherokees use a PSX24W or 9005 bulb for the DRL, but it’s vital to check your owner’s manual or inspect the existing bulb before buying a replacement. Getting the wrong bulb can lead to fitment issues or electrical problems.
Tools And Materials Needed
Before starting, gather the right tools and parts. This makes the job smoother and prevents unnecessary trips to the store.
- Replacement DRL bulb (PSX24W or 9005, confirm your specific fitment)
- Flathead screwdriver
- 10mm socket and ratchet
- Protective gloves (to avoid oil from your skin damaging the bulb)
- Microfiber cloth (for cleaning lens or hands)
- Owner’s manual (for reference)
- Flashlight (for better visibility in tight spaces)
It’s also smart to have a small container or magnet tray for holding screws so they don’t get lost.
Step-by-step Guide To Changing The Daytime Running Light
Follow these steps to change the DRL on your 2017 Jeep Cherokee without damaging any parts:
1. Park And Prepare
Start by parking your Cherokee on a flat surface. Turn off the engine and remove the key.
If you recently drove, wait for the headlamp assembly to cool down, as it may be hot.
For extra safety, disconnect the negative battery terminal with a 10mm socket. This reduces the risk of electrical shorts or accidental shocks.
2. Locate The Drl Bulb
Open the hood and look for the back of the headlight assembly on the side with the faulty DRL. The DRL bulb socket is usually on the outer edge, separate from the main headlight.
On some trims, the DRL may be accessed from behind the wheel well rather than through the engine bay. If space is tight, turning the steering wheel away from the side you’re working on can help.
3. Remove The Old Bulb
Gently turn the DRL bulb socket counterclockwise to unlock it. Pull the socket straight out don’t force it.
If it’s stuck, wiggle gently or use a flathead screwdriver to help release the tabs.
Carefully pull the bulb out of the socket. If it’s difficult to grip, use gloves for better traction.
4. Install The New Bulb
Wipe the new bulb with a microfiber cloth before installing. Any oil or dirt can cause the bulb to burn out early.
Insert the new bulb into the socket, ensuring it clicks into place. Reinsert the socket into the headlamp assembly and turn clockwise to lock it.
5. Test The New Bulb
Reconnect the battery. Start the engine and check if the new DRL works.
If it does not light up, double-check the bulb orientation and electrical connections.
6. Reassemble And Clean Up
Secure any loose wiring or covers you removed. Make sure everything fits snugly and no tools are left behind. Close the hood.
Non-obvious insight: Many owners forget to check the rubber gasket around the bulb socket. If it’s cracked or missing, moisture can enter the headlamp and shorten bulb life. Replace the gasket if needed.
Another tip: After replacement, check the DRL beam pattern on a wall. If the light seems scattered, the bulb may not be seated correctly.
Comparing Bulb Types
It’s tempting to upgrade to LED bulbs for longer life and brighter light. However, not all LEDs are compatible with the 2017 Cherokee’s electrical system. Here’s a brief comparison:
| Bulb Type | Lifespan (hours) | Brightness (lumens) | Compatibility |
|---|---|---|---|
| Halogen (PSX24W/9005) | 350-500 | 1000-1700 | 100% (OEM) |
| LED | 10,000+ | 2000-4000 | Varies (may need resistor) |
Caution: Using aftermarket LEDs without proper resistors can trigger a dashboard warning or cause flickering.
Common Mistakes To Avoid
Changing the DRL is straightforward, but these mistakes can lead to extra work or damage:
- Touching the bulb glass: Oils from your skin can cause hot spots and early failure.
- Forcing the socket: If it doesn’t turn easily, check for release tabs or debris.
- Mixing up bulbs: The DRL and headlight bulbs look similar but have different functions and sockets.
- Skipping the battery disconnect: Even if the car is off, residual power can short electronics.
- Ignoring water seals: A missing seal can cause condensation inside the headlight.
Cost Of Replacing Daytime Running Lights
If you do it yourself, a halogen DRL bulb usually costs between $10 and $25. LED upgrades may run $40 to $60 per bulb, plus any required resistors.
Professional replacement at a dealership or shop can cost $80 to $120 with labor. The biggest factor is labor time, as some trim levels require removing extra panels for access.
Maintenance Tips For Longer Bulb Life
Getting the most out of your new DRL bulbs comes down to a few smart habits:
- Clean the headlamp lens regularly. Dirt and haze can reduce light output and heat up the bulb.
- Avoid high-pressure washing near the lights, as water can force its way into the housing.
- Check bulb fitment during oil changes or other routine maintenance. A loose bulb can vibrate and wear out connections.
- Use gloves for all bulb handling to prevent fingerprints.
Troubleshooting: Drl Still Not Working?
If your new bulb doesn’t light up, try these steps:
- Double-check the bulb type: Wrong bulbs won’t work or may fit loosely.
- Inspect the fuse: The DRL circuit has a dedicated fuse. Check your owner’s manual for the exact location.
- Look for wiring damage: Rodents or age can cause broken wires near the headlamp.
- Swap sockets: If possible, try the new bulb in the other side’s socket to rule out a defective bulb.
- Check for software issues: Some Cherokees may need a system reset after bulb changes.
If none of these steps work, consult a dealer or certified mechanic.
2017 Jeep Cherokee Drl Access Points Comparison
Different trims may have unique headlight designs. Here’s a quick comparison:
| Trim | DRL Access | Extra Steps |
|---|---|---|
| Latitude | Engine bay | None |
| Limited | Wheel well | Remove liner clips |
| Trailhawk | Engine bay | Tight fit |
When To See A Professional
While changing a DRL bulb is usually a DIY job, seek help if:
- The headlamp housing is foggy or full of moisture (may need resealing).
- The bulb socket is melted or corroded.
- You see a dashboard error that won’t clear after replacement.
- You’re uncomfortable with electrical work or tight spaces.
A professional can also help with LED upgrades or custom DRL setups, ensuring no electrical faults.
Environmental Impact Of Used Bulbs
Halogen bulbs contain small amounts of metal and glass that can be recycled. Never throw used bulbs in regular trash.
Most auto parts stores offer recycling bins. LED bulbs last much longer and reduce waste, but may contain more complex materials.
