Here's a general guide. Specific details might vary slightly depending on your exact trim level. Always consult your owner's manual for the most accurate instructions for your vehicle.
Steps:
1. Prepare the area: Find a well-lit workspace. You'll likely need a Phillips head screwdriver and possibly a trim removal tool (plastic pry tool to avoid scratching).
2. Access the third brake light: On a 2005 Mustang convertible, the third brake light is usually accessed from inside the trunk. Open the trunk.
3. Remove interior trim: You'll need to remove the interior trim panel above the rear window. This typically involves carefully prying off the trim panel using a plastic trim removal tool. Start at the edges and work your way around, being gentle to avoid breaking any clips. There might be screws holding parts of the trim in place as well. Carefully examine the area to locate these clips and screws.
4. Disconnect the electrical connector: Once the trim panel is removed, you should see the brake light assembly. Carefully disconnect the electrical connector from the back of the light assembly. Take note of how it connects to easily reconnect it later.
5. Remove the brake light assembly: There are likely screws or clips holding the brake light assembly in place. Remove these fasteners carefully. The assembly may be a single unit or have multiple parts.
6. Install the new brake light assembly: Carefully install the new brake light assembly, ensuring it's properly seated and all fasteners are secure.
7. Reconnect the electrical connector: Carefully reconnect the electrical connector to the new brake light assembly.
8. Reinstall the trim panel: Reinstall the interior trim panel, making sure all clips and screws are properly secured.
9. Test the brake light: Close the trunk and test the brake light to make sure it's working correctly. Turn on the car and then step on the brake pedal.
Important Considerations:
* Take Pictures: Before you start disconnecting anything, take pictures of the process. This will help you remember how everything goes back together.
* Gentle Pressure: Use gentle pressure when removing trim pieces to avoid breaking any clips.
* Replacement Part: Ensure you purchase the correct replacement third brake light for your 2005 Mustang convertible.
* Professional Help: If you are uncomfortable performing this repair yourself, consider taking your vehicle to a qualified mechanic.
