I have a 2000 Pontiac Grand Prix, and at about 3 AM every morning, the alarm will randomly go off when no one is around. Can the cold weather casue this to happen?
Yes, I have the exact same car and the factory alarm is VERY sensitive. Mine will go off during a heavy rain, a clap of thunder, a gust of wind, or if a loud motorcycle drives by. If you lock the car with the power lock switch on the door the alarm won't set. In your owner's manual there's a procedure to adjust the sensitivity of the alarm as well. HTH. -Jim
