How do you replace the light on the on-off buttons for cruise control in a 1999 Ford Explorer?

On the backside of your steering wheel there are two screws you need to remove. These are covered over with circular covers which you can easily remove. Having removed the 2 screws you can gently remove the whole unit which contains the air bag. You will see the control switches for your cruise control and your light bulbs for your cruise control (octagon like head - may be blue in color). You can turn this counter clockwise and lift off. The cruise controls may also be released from their switches by gently pulling apart (should you have need to replace them) . Some people remove these when the rubber touch pads get old however they are needed to keep your horn grounded. It is basically removing only two buttons in the back of your steering wheel and the rest is a breeze. Hope this has been helpful.
