So about two years ago my 03 4dr blazer had this problem where the alarm would just go off in the middle of the night for no reason. After awhile it kind of just stopped on its own. Then the other day it started to do it again. I'm thinking it's a winter issue because it has never done this during warm weather. Well when it did it on Thursday I went out made sure all the doors were shut tight. After about 20 min the alarm went off again. this time I simply unlocked the doors and went on with my night. That brings me to today. I go to start her up so I can go to work and she's dead. When I say dead I mean dead dead. No interior lights, noise, or anything. If anyone has any idea as to what this may be please let me know. I ordered all 4 of the door switches when this happened the last time but I never got around to replacing them seeing as the problem stopped.

I forgot to mention the alarm is just the standard factory alarm where it should only go off if the doors were locked outside and it's being unlocked from the inside.
