2000 dodge ram 1500 help

hello, i've got a guy comming next week who someone put in a pioneer cd player along with an XM radio, that all works fine but the guy doesn't have his power mirrors or interior dome light, the light is good, all fuses are good (tested each one) all wiring in for the cd player is good,  the defroster for the mirros still works along with all the other lights inside the cab,  even if you turn the dome light on by using the switch it still doesn't work,  i'm just wonding if anyone else has run into this or has some helpful advice,  i was told maybe the BCM is fried? anyone?

Check to see if the constant power wire from the deck is good as well. I had this exact thing happen to a 1998 Dodge 1500 and I just ran another constant wire to the constant wire behind the radio and all functions were back to normal. For some reason, the constant power wire is linked to all the mirrors, dome light and door locks as well.Jeff
