How to replace the Brake Light Switch on Buick Lucerne?

The first step to replace the stop lamp switch is to remove the left sound insulator. To remove the stop lamp/ABS/shift lock switch you must turn it counterclockwise and pull it out before disconnecting its electrical connector. Install the stop lamp switch in fully locked position since the twist lock version needs no readjustment during this step. Press the stop lamp switch into its retainer until the button enters the switch barrel completely. Turn the switch clockwise to its locked place. Attach the electrical connector of the stop lamp/ABS/shift lock switch to the stop lamp switch and modify the switch position if required. Finally, reinstall the sound insulator.
