Dome Lights

I CAN NOT GET MY DOME LIGHTS TO WORK WILL SOMEONE PLEASE HELP?ALL of my dash lights,park.head,backup lights all work stereo all work.checked fuses they all are good put new one in for dome lights anyway just to make sure. They will not turn on by pushing the to buttons or turning roller under headlights. its a 1997 it has 165,235 miles on it bought it at 160,000 never had wax on it i changed out original plugs & wires put all new front end all the woman that owned did was drove it well she did get oil changed ever 2000 miles but thats all she had wrote down looks brand new inside and out now after i put wax on it . It is a SE 3.8 not super charged and the power is amazing for that many miles. I gave 950.00 for it but it blue books for 3,600 dollars all power. could someone tell me is this a good deal or is engine going to die soon i keep oil changed at ever 2000 like she did or is it worth putting a little more money in like i said great power uses no oil or did i go wrong putting new front end? can someone give me a suggestion on lights and keep or sail? thanks
