04 M45 power windows, locks, and mirrors not working

[PDX_M45]

Help! My power windows, locks, and mirrors have stopped working. I don't know if it is related to this, but a couple of weeks ago my power seat started acting up also, but now seems fine. I have checked all of the wires and fuses and all are visibly ok. I am leaning toward the BCM, but I don't know. Has anybody had any similar issues??

Be sure to check all your fuses real good, I had all interior power things including lighting go out while installing a set of dome lights that were reverse polarity on one of my previous M's!! May not be related but in my case one of the fuses had tripped everything "power" off!!
