Ok I have a draw in my electrical system and have it narrowed down to the speedo fuse. Quick history my truck didn't come with factory keyless so I changed my tailgate control module and my BCM from another trailblazer that came factory with keyless, after installing it my dash wouldn't light up I found out I have to have it programmed to the truck with a tech 2. I switched it back out with my original stuff and ever since I did this my batt dies after two days. Iam hopping somebody can help me with this I live in Virginia beach if somebody has answers please get ahold of me on here or text me at 518-451-0107 thanks for the help
