Tools You'll Need:
* Wrench (likely 11mm or 13mm): Check your owner's manual or consult a repair manual specific to your 1999 Malibu to confirm the correct size.
* Socket wrench and extension (optional but helpful): Provides better leverage, especially in tight spaces.
* New brake light switch: Ensure you purchase the correct replacement part for your 1999 Chevy Malibu. Your VIN number is the best way to ensure compatibility.
* Phillips head screwdriver (possibly): Some models might require removing a cover to access the switch.
* Gloves (recommended): To keep your hands clean.
* Rag or shop towels: To clean up any spills.
* Owner's Manual: It might have diagrams or specific instructions.
Steps:
1. Disconnect the Battery: This is the MOST IMPORTANT step. Locate the negative (-) battery terminal and disconnect it using a wrench. This prevents accidental short circuits and potential damage to your vehicle's electrical system.
2. Locate the Brake Light Switch: The switch is typically located on the brake pedal assembly, usually under the dash. You'll likely need to reach under the dash from the driver's side. It's a small cylindrical switch with electrical connectors. It might be somewhat difficult to see; a flashlight will help.
3. Disconnect the Electrical Connector: Carefully unplug the electrical connector from the brake light switch. There's usually a small clip or tab that needs to be pressed or released to disconnect it.
4. Remove the Switch: Use the correct wrench size to remove the brake light switch from its mounting bracket. It usually unscrews. Sometimes there's a retaining clip involved, so check carefully before applying too much force.
5. Install the New Switch: Carefully align the new brake light switch with the mounting bracket and screw it in tightly, ensuring it's firmly seated. Don't overtighten.
6. Reconnect the Electrical Connector: Carefully plug the electrical connector back onto the new brake light switch, making sure it's securely connected.
7. Reconnect the Battery: Reconnect the negative (-) battery terminal.
8. Test the Brake Lights: Turn on the ignition and depress the brake pedal. Your brake lights should illuminate. If not, double-check all connections. If the problem persists, there might be a more significant issue in the brake light circuit.
Important Considerations:
* Access: Access to the brake light switch can be tight. You might need to use a mirror or flashlight to get a good view. Flexibility is helpful!
* Correct Part: Always ensure you're using the correct replacement brake light switch for your specific 1999 Chevy Malibu. A wrong part could lead to further problems.
* Manual: Refer to your owner's manual or a repair manual specific to your vehicle model for diagrams and detailed instructions. These manuals may provide better visual guidance and specific torque specifications.
If you're uncomfortable performing this repair yourself, it's best to take your vehicle to a qualified mechanic. They have the tools and expertise to complete the job safely and efficiently.
