Swtill nothing power to the switch but still no power to the mirrors could this possilbly be the bcm giving an issue

If power is going to the switch but no power coming from the switch then the switch itself needs replaced. the BCM has nothing to do with the power mirrors. circuit diagram is below of your vehicle's power mirror's.
