I have a 2003 pathfinder le. Everytime I turn on the car my parking lamps and rear break lights turn on (I refer to this as parking light mode). Now I have the headlight switch turned to off and the sensor in the windshid isn't blocked. The light switch works in the other modes but no matter what I do I can't get the parking light mode to go off. What can it be? The lights do turn off when I shut the car off.
