I re-checked all the electrical connectors and fuse tested good.
Thanks for the help.
Is there a voltage drop across the bcm fuse? Should be if the BCM's getting juice. 0 drop means no current flow, expecting a couple mV, just a quick and fast test.
Check out connector x326 and check off what's NOT working with all the wires going through that thing.
