    What is the difference in Brake Light Switch installation for 2000 Cadillac Sevilles compared to 2006 and later models? Posted by Rylee K.
    A:
    For vehicles from 2006 and later, a Brake Pedal Position (BPP) sensor is used, which requires a calibration procedure performed by a dealership service department or professional repair facility equipped for the necessary programming.

    Q:
    How do you install a new Brake Light Switch in the 2000 Cadillac DeVille? Posted by Uelle P.
    A:
    For installation, connect the electrical connectors to the switch and push the new switch into the clip until the switch plunger is fully depressed. Rotate the switch clockwise until it locks into position and no further adjustment is needed. Ensure that the brake lights are functioning properly. The rest of the installation process is the reverse of the removal. You can Select Your Vehicle to see complete installation and repair tips.
