1. Identify the Problem:
* Symptoms: Does your brake lights not work? Does your cruise control not work (if equipped)? Does your brake warning light illuminate constantly? These are all symptoms of a potentially faulty brake switch.
* Locate the Switch: The brake switch is usually mounted on the brake pedal assembly, often near the firewall. It's a small, cylindrical switch that's actuated by the brake pedal. You'll likely need to get under the dash to access it easily.
2. Gather Tools:
* Socket Set: You'll need the correct socket size to remove the switch (likely a small nut or bolt).
* Screwdriver (possibly): Some switches might require a screwdriver to disconnect a connector.
* New Brake Switch: Purchase a replacement brake switch that's compatible with your 1981 Dodge Prospector. The part number can often be found in a repair manual or online parts catalog. It's crucial to get the correct replacement.
* Wrench (possibly): Depending on the location and mounting, you might need a wrench.
* Test Light (optional but highly recommended): This will help you verify if the problem is truly the switch before you replace it.
3. Disconnect and Remove the Old Switch:
* Disconnect the Electrical Connector: Carefully unplug the electrical connector from the old switch.
* Remove the Switch: Unscrew the nut or bolt holding the switch in place. Carefully remove the old switch.
4. Install the New Switch:
* Install the New Switch: Carefully insert the new brake switch into its mounting location.
* Secure the Switch: Tighten the nut or bolt to secure the new switch firmly in place. Don't overtighten.
* Reconnect the Electrical Connector: Carefully plug the electrical connector back into the new switch.
5. Test the Repair:
* Turn the Ignition Key to the "On" Position: Do not start the engine.
* Press the Brake Pedal: Your brake lights should illuminate. If they do not, there's another problem in the circuit. Use your test light to check for power and ground at the switch to pinpoint the exact issue.
* Test Cruise Control (if equipped): If your Prospector has cruise control, test its functionality.
Important Considerations:
* Safety First: Always disconnect the negative battery terminal before working on electrical components.
* Repair Manual: A repair manual specific to your 1981 Dodge Prospector is invaluable. It will provide detailed diagrams and instructions for your vehicle's specific brake switch location and installation.
* Test Before Reassembly: Before reassembling everything, test the new switch to ensure it's working correctly.
* Other Possibilities: If the brake lights still don't work after replacing the switch, the problem could be a blown fuse, a faulty brake light bulb, wiring issues, or a problem with the brake light circuit itself. Systematic testing is crucial.
If you are not comfortable working on your vehicle's electrical system, it's best to take it to a qualified mechanic. Incorrectly wired brake lights are a serious safety hazard.
