1. Gather Tools:
* Screwdriver (likely Phillips head, but check to be sure)
* Possibly a trim removal tool (plastic pry tool to avoid scratching)
* New third brake light assembly (ensure you get the correct one for your year and model)
* Rag or towel (to protect the interior)
2. Access the Third Brake Light:
* Interior Access (Most Likely): For most Rendezvous models, access is from inside the vehicle. Open the rear liftgate. You'll likely find the brake light assembly housed in a trim panel at the top of the liftgate.
* Exterior Access (Less Common): Some models *might* require removing the exterior trim around the light, but this is less common.
3. Remove the Old Brake Light:
* Locate the fasteners: Carefully inspect the area around the brake light. You'll likely find screws or clips holding the light assembly in place. The screws might be hidden behind trim pieces or under plastic covers.
* Remove the fasteners: Gently remove the screws or carefully pry off any clips using a trim removal tool if necessary to prevent damage. Be careful not to break any plastic clips.
* Disconnect the electrical connector: Once the fasteners are removed, the light assembly should come loose. Disconnect the electrical connector from the back of the light assembly. Gently pull it apart; don't yank on the wires.
4. Install the New Brake Light:
* Connect the electrical connector: Carefully connect the electrical connector to the new brake light assembly.
* Secure the new assembly: Align the new brake light assembly and carefully secure it with the screws or clips you removed earlier.
* Reinstall any trim pieces: Reattach any trim pieces you removed to access the brake light.
5. Test the New Brake Light:
* Close the liftgate and test the new brake light by pressing the brake pedal. Ensure it illuminates correctly.
Important Considerations:
* Year and Model: The exact procedure may vary slightly depending on the year and model of your Buick Rendezvous. Consult your owner's manual for the most accurate instructions specific to your vehicle. A repair manual specific to your year may also be beneficial.
* Caution: Be gentle when working with plastic parts to avoid breaking them. A trim removal tool can help prevent damage.
* Electrical Connection: Be sure the electrical connector is properly seated to avoid electrical problems.
If you are uncomfortable performing this repair yourself, it's always best to take your vehicle to a qualified mechanic. They have the tools and expertise to complete the job safely and efficiently.
