Small Trick to maybe get PRND123 to work Buick Century Custom.

This is a small trick that may get your PRNDLE or Park, Reverse, Neutral, Drive, 1, 2 ,3. to light up if it does not work. This is not a fix, but if you need to see the mileage on your car or if you can't see after dark then this may help you. My girlfriends car's prndle has not worked since she bought the car, and once in a blue moon it would light up. I tried this method 3 times today and it worked all three times. I hope this helps someone out. She has a 2001 buick century custom.
