Hey guys

I know this is g35 forum and all. However what would cause a BCM to go bad? a few years ago my friend blew his out when tryin to install an alarm. Now yesterday I had my car parked all day..didnt touch it until work was over... i start the car and none of the wipers,windows,ac,headlamp works. He said it might be the BCM since he had those issues but how can it just go bad like that? I have a 2004 v35 sedan,

When mine went out, it was all my door locks that didn't work.
