Car repair
I have a Mercury Sable LS 2000 The lights on the Dash Board that display the gear you are in are not working I was told that I need to change a modal any ideas

On many newer cars it is fairly easy to pull the whole dash cluster out. Maybe remove a hidden screw or 2 and then pull or pry in the right place. Do I know exactly where? No. Once out, locate the lights and check to see the module is getting power. If it is, remove it and take it top a parts store and buy a new one. For a specialized item like that, you may have to go to a dealer or junk yard. A junk yard might even let you watch somebody remove the one they are selling you.
