Have you done any testing with a voltmeter before changing anything? Are you aware the BCM may be part of the circuit.

Yes I'm not getting any power to the fuss which tells me the problem is somewhere under the dash I figer. I can't get wiring diagram or the dash so I can chase down why no power ( broken wire or lose ground)
