For the Lower Brake Lights (on the taillights):
1. Safety First: Park on a level surface, engage the parking brake, and turn off the vehicle. It's best to let the bulbs cool down if they've been on for a while.
2. Access the Taillight: You'll usually need to access the taillight assembly from the inside of the vehicle. This typically involves:
* Removing an access panel or trim piece inside the cargo area (for the rear lights). This often involves unscrewing a few screws or fasteners.
* Carefully unclipping any plastic coverings. Be gentle to avoid breaking them.
3. Disconnect the Bulb: Once you have access to the bulb socket, you may need to:
* Twist: Gently twist the bulb socket (usually a quarter-turn) to disconnect it from the light housing.
* Unclip: Sometimes there's a small retaining clip holding the socket in place; carefully release this.
4. Remove the Bulb: The bulb is likely held in place by a small socket. Gently pull the bulb straight out. Do not touch the glass part of the bulb; use a clean cloth or paper towel to handle it.
5. Install the New Bulb: Carefully insert the new bulb, making sure the prongs on the bulb align with the sockets in the housing. Gently push it into place until it clicks or is firmly seated.
6. Reconnect and Reassemble: Reconnect the bulb socket, making sure it's securely fastened. Reinstall the access panel or trim pieces you removed, ensuring everything is properly secured.
7. Test the Lights: Turn on your brake lights to verify that the new bulb is working correctly.
For the Center High-Mounted Stop Lamp (CHMSL - Third Brake Light):
1. Access the CHMSL: This usually requires opening the rear hatch or tailgate and accessing the light from the inside of the vehicle. There's typically a panel or cover held in place by clips or screws.
2. Remove the Lens: Carefully remove the CHMSL lens. This might involve carefully prying it open with a plastic trim removal tool (avoid metal tools to prevent scratches).
3. Remove and Replace the Bulb: The bulb socket is usually accessible once the lens is removed. Follow steps 3-5 for the lower brake lights (disconnect, remove old, install new, reconnect).
4. Reassemble: Reinstall the lens and any panels you removed.
5. Test the Lights: Verify the new bulb works.
Important Considerations:
* Bulb Type: Ensure you purchase the correct type of bulb for your 2002 Chevy Suburban. Your owner's manual will specify the correct bulb type (e.g., 1157, 3157). Auto parts stores can help you find the right one if you provide them with your vehicle's year, make, and model.
* Grounding: Sometimes a poor ground connection can cause brake light problems. Make sure the bulb socket and its connections are clean and properly grounded.
If you're not comfortable performing this task yourself, it's best to take your vehicle to a qualified mechanic. Improperly installed bulbs can lead to safety hazards.
