So my room mate wakes me up this morning and says one of my parking lights is on...so i go out side(its for some reason snowing by the way)and the front left parking light is on nothing else.I turned on and off the lights,tried the turn signals it does not blink(back does),then disconnected the battery and reconnected it...still on.any one know what would cause this?

 

Check to see if your floor is damp on the passengers side. In fact, check all carpet areas for signs of water leaks. If water is leaking on electrical contacts, it causes all kinds of weird problems. There is a TSB on it, 07-14-06.

 

Any water leaks? Some S197's have had issues where water got into the ECM/junction box and caused freaky electrical issues. Take it back to the dealer if you are still under warranty.

EDIT: I see Sandy beat me by about 1 minute!

 

The water leak has molded your carpet and corroded the smart junction box
that controls most electrical lighting functions and other things.
