Tools You'll Need:
* Socket wrench (likely a 13mm or 7/16 inch)
* Ratchet
* Extension (may be necessary)
* New brake light switch (ensure you get the correct one for your model)
* Shop rags or paper towels
* Possibly a small flat-head screwdriver (to pry gently if needed)
Procedure:
1. Safety First: Engage the parking brake firmly. Disconnect the negative terminal from your battery to prevent accidental shorts.
2. Access the Brake Pedal: You'll need to access the brake pedal assembly. This usually involves working under the dashboard. You might need to remove the lower dash panel or parts of it to get enough room to work. Consult your repair manual for specific panel removal instructions.
3. Locate the Brake Light Switch: The switch is typically located on the brake pedal assembly itself. It's a small cylindrical device often with a single electrical connector.
4. Disconnect the Electrical Connector: Carefully unplug the electrical connector from the brake light switch. Sometimes a small tab needs to be pressed to release the connector.
5. Remove the Switch: Use your socket wrench and ratchet to remove the nut or bolt that secures the brake light switch to the brake pedal. The switch should then pull straight out. You might encounter some resistance. If so, gently work it free. Avoid excessive force.
6. Install the New Switch: Insert the new brake light switch into the same location. Make sure it is seated correctly. Tighten the nut or bolt securing it to the brake pedal. Don't over-tighten.
7. Reconnect the Electrical Connector: Carefully plug the electrical connector back into the new brake light switch.
8. Reassemble: Reinstall any dash panels or parts you removed to access the brake pedal.
9. Test: Reconnect the negative battery terminal. Test your brake lights to ensure they are working correctly. With the ignition on, press the brake pedal and check the brake lights. If they don't work, double-check all connections.
Important Considerations:
* Bleeding the Brakes (Possibly): In some cases, removing the brake light switch could introduce air into the brake system. While unlikely, it's a good idea to check your brake fluid level and consider bleeding your brakes afterward if you notice any issues with your braking performance.
* Repair Manual: This is a general guide. A repair manual specific to your 2002 Chevy Suburban 1500 is strongly recommended. It will provide detailed instructions and diagrams, avoiding potential mistakes.
* Professional Help: If you are not comfortable performing this repair yourself, take your vehicle to a qualified mechanic. Improperly installed brake components can be dangerous.
