Lights that unpredictably stay on



I have a 2002 L300 Saturn sedan with approx 110K miles on it. Recently I noticed that the lights stay on when the keys are removed. I have troubleshooted with almost everything & I think that the switch on the indicator stick is having some difficulty. Instead of disarming the battery I pulled the fuse for the headlights out until I can fix the problem. (to save the battery)
