Gather Your Tools and Materials

Before you start, ensure you have the necessary tools and materials:

• New Headlight Bulb: Choose a bulb that matches the specifications of your Jeep Grand Cherokee model year. You can find this information in your owner’s manual or online.
• Phillips Screwdriver: You’ll need a Phillips screwdriver to remove the screws holding the headlight assembly in place.

Locate the Headlight Assembly

The headlight assembly is located behind the front grille of your Jeep Grand Cherokee. To access it, you’ll need to open the hood:

1. Open the Hood: Release the hood latch located inside the vehicle.
2. Lift the Hood: Carefully lift the hood and prop it open using the hood prop rod.

3. De-Connect the Electrical Connector: Locate the electrical connector that connects to the headlight bulb. Gently pull it out of the socket.
4. Remove the Headlight Assembly: Once the screws are removed and the electrical connector is disconnected, you can gently pull the headlight assembly forward to remove it.

Replace the Headlight Bulb

Now that you’ve removed the headlight assembly, you can replace the burnt-out bulb:

1. Locate the Old Bulb: The headlight bulb is located inside the headlight assembly.
2. Remove the Old Bulb: Carefully remove the old bulb by twisting it counter-clockwise.
3. Install the New Bulb: Insert the new bulb into the socket and twist it clockwise until it’s securely in place.
4. Reconnect the Electrical Connector: Connect the electrical connector back to the headlight bulb.

6. Secure the Screws: Secure the screws that hold the headlight assembly in place.

Test the New Headlight Bulb

After reassembling everything, it’s time to test the new headlight bulb:

1. Turn on the Headlights: Turn on your car’s headlights and check if the new bulb is working.
2. Check for Proper Alignment: Ensure the headlight beam is properly aligned. If not, you can adjust it using the headlight adjustment screws located on the back of the headlight assembly.

Final Touches and Safety Tips

• Dispose of the Old Bulb Properly: Headlight bulbs contain mercury, so dispose of the old bulb properly according to your local regulations.
