General Steps (May Vary Slightly):
1. Safety First: Engage the parking brake firmly. Disconnect the negative battery terminal to prevent accidental short circuits.
2. Access the Switch: The brake light switch is usually located on the brake pedal assembly, often underneath the dash, near the firewall. You'll likely need to access it from under the dash. This might involve removing some plastic panels or covers. You may need a socket set and possibly a ratchet to remove these.
3. Disconnect the Electrical Connector: Locate the electrical connector plugged into the switch. Carefully unplug it. Sometimes a small tab needs to be depressed to release the connector.
4. Remove the Switch: The switch itself is usually held in place by a single nut or bolt. Use the appropriate wrench (usually a small socket) to remove the fastener. The switch itself might have a clip or other retention mechanism – carefully examine how it's held in place before forcefully pulling on it.
5. Install the New Switch: Carefully install the new brake light switch, ensuring it's seated correctly and the fastener is tightened appropriately. Do not overtighten.
6. Reconnect the Electrical Connector: Plug the electrical connector securely back onto the new switch.
7. Reassemble: Replace any panels or covers you removed to access the switch.
8. Test: Reconnect the negative battery terminal. Test the brake lights to ensure they are working correctly by pressing the brake pedal.
Important Considerations:
* Variations: The exact location and access method might vary slightly depending on the specific year, model, and trim level of your 1997 Chevy pickup.
* Tools: You'll likely need basic hand tools, including sockets and wrenches.
* Bleeding Brakes (Unlikely, But Possible): In rare cases, removing the brake light switch might slightly disturb the brake system. If you experience any spongy brakes after the replacement, you may need to bleed the brakes. This is best left to a mechanic unless you are experienced with brake bleeding.
If you're uncomfortable performing this repair yourself, it's always best to take your truck to a qualified mechanic. It's a relatively simple job, but a mistake could lead to brake light malfunction and potentially safety hazards.
