In cold weather, usually in the middle of the night, the door lock disengages and the door ajar light turns on, and usually the alarm goes off. If I don't go out and shut the door tightly, the light may stay on all night without my knowledge and in the morning the battery is dead. What is this???
A bad door latch switch. The hard part is diagnosing which door.

If you use your keyfob to lock the doors, it will activate the alarm, and you will need to unlock with the keyfob. If you lock the doors with the lock button on the inside of the door, it should not activate the alarm.

Hi
Make sure all door switches are functioning properly. See that each switch pushes in and out, without sticking.

i would suggest you recharge the battery overnight, this should stop the hazzard lights activating as they do when battery level is too low.
