Electric problem!

Hey guys, so im new to this whole forums thing and I need some help asap. I recently purchased a 2011 cruze Eco, and I just hit 70K miles. My problem is that my radio is completely dead, my passenger side front turn signal isn't working, but the left one wirks just fine. Also, my left rear tail light isn't working. So I thought, whatever no big deal the globes are burned out. So I put brand new globes all the way around and still having the same issues. Also I tested all the fuses and relays with my voltmeter and also with a relay tester. Everything checks out fine which causes me to believe that the BCM is toasted. Any thoughts before I take it to the dealer?? Thanks.
