2000 Grand Marquis lighting gremlin
 

I replaced the LCM in an attempt to stop dome/floor/auto headlights (when selected) from turning on randomly throughout the night when the car is off... What's next... the headlight switch? and how easy or difficult is that to change? Lastly, it almost seems to behave as if I just hit the door unlock button on the fob... Already on the second battery.
