i bought an 03 suburban that i was told didn't run as a result of a bad bcm. i finally towed it home and put a battery in it but am not really sure how to diagnose whether it's actually the bcm (they're a little expensive to just throw at the suburban without verification first). i put the key in and turn it to accessory and there is a constant loud buzzing noise under the hood...i'm not sure what exactly the noise is and it's got me a little confused right off because my 03 sierra doesn't do anything of the sort
when i turn the key...i get nothing happening at all. i'm pretty new to gm trucks as i just bought my first (the sierra) in march and now this suburban
another pic of my sierra just because lol
