  1. 1

    Open up the bonnet of your Buick Century and locate the battery. Use a wrench to remove the clamp bolt on the negative terminal. Lift the battery cable off the negative terminal.

  2. 2

    Sit in your drivers seat. Place your hands round the back of the steering wheel until you locate the tab which allows you to adjust the height of the steering wheel. Lower the steering wheel to its lowest possible position within the column. This will provide you with the best access to the instrument panel.

  3. 3

    Find the rubber bezel which is around the instrument panel. Use a Phillips-head screwdriver to remove the two screws which hold it in place. Pull the bezel off the dash and place it in the glove compartment for reattachment later.

  4. 4

    Take off the three screws which fix the instrument panel to the dashboard. Slide the panel half way out of the dash. Reach around the back of the panel until you locate the electrical connector. Pull the electrical connector out of the back of the panel. Remove the instrument panel from the vehicle and place on a clear work surface.

  5. 5

    Unscrew the broken LED bulbs in a counterclockwise direction until they come free from the instrument panel. Discard the bulbs in either the trash or recycling. Insert the new bulbs by turning them in a clockwise direction in the panel. Keep turning them until they can no longer turn anymore to ensure they are firmly in place.

  6. 6

    Reattach the instrument panel and bezel to the dashboard by following the removal steps in reverse. Place the negative cable back on its respective battery terminal and fix in place with the clamp bolt. Turn on the engine to check that the instrument panel and its bulbs now work correctly.
