To find it:
1. Look under the dash: The easiest way is to look under the dashboard, near the brake pedal. You'll likely see a small switch connected to the brake pedal linkage. It might be directly on the pedal arm itself or on a bracket nearby.
2. Follow the brake light wires: If you can't spot it visually, trace the brake light wiring harness. The wires leading to the brake lights will connect to the switch.
Replacing it:
Replacing it is generally a straightforward job but can vary slightly depending on the exact model of your 1998 Chevy pickup. You'll likely need:
* A new brake light switch: Make sure you get the correct one for your specific truck model. Your local auto parts store (like AutoZone, Advance Auto Parts, or O'Reilly Auto Parts) can help you find the right part using your VIN.
* A small socket wrench or pliers (depending on the switch type): to remove the old switch.
Before you start:
* Disconnect the negative battery terminal: This is crucial to prevent accidental shorts and potential damage.
General steps (but consult a repair manual for your specific truck for precise instructions):
1. Disconnect the electrical connectors: Carefully unplug the electrical connector(s) from the old brake light switch.
2. Remove the old switch: Use a socket wrench or pliers to remove the switch from the brake pedal assembly. Note how it's installed so you can put the new one in correctly.
3. Install the new switch: Install the new switch, ensuring it's properly seated.
4. Reconnect the electrical connectors: Carefully plug the electrical connectors back into the new brake light switch.
5. Reconnect the battery terminal: Reconnect the negative battery terminal.
6. Test the brake lights: Test your brake lights to ensure they're working correctly.
Important Note: If you're not comfortable working on your vehicle, it's best to take it to a qualified mechanic. Improper installation can lead to brake light malfunctions, which can be a safety hazard. A repair manual specific to your year, make, and model of Chevy pickup will provide the most accurate and detailed instructions.
