Hey guys,
My 2000 Chevy blazer's factory security alarm goes off randomly during the night, nothing provokes this to happening. I've had a security camera set up and watching the truck for many days. I currently have to leave the horn fuse unplugged so i do not disturb the neighbors anymore! Along with this issue, is that my interior dome lights do not shut off once i close the doors. I have to have my dome override on all the time to stop my battery from draining. If anyone has any insight to as why this could be happening that would be amazing.

Thanks in advanced guys!

 

I would start by checking the door switch. That is one thing that could cause both problems.

 

Thanks man! ill hopefully be checking into that this weekend!
