I am attaching the info on the BCM for this vehicle.

However, I would suggest testing the voltage on one of these things that is not working because it is most likely not the BCM.

This vehicle has a door module that will control each of these items so I would pick the mirror and see if you have voltage coming out of the PDM but voltage going in to the PDM from the switch.

I am attaching the info below on this for your review.

Let me know if you have questions on this.

Thanks
