My twilight sentinel and daytime running lights drains my battery if I leave the switch on overnight; however, once I charge the battery the car starts and the daytime lights work, but when i press the power door locks to lock they fluctuates til I hit the keyless remote. So I have been keeping the twilight sentinel off and the battery is good the next day.what's wrong?
