It sounds like the BCM is out which controls both of these systems. To be sure lets do a CAN scan which is the future of automotive repair. you can get a CAN scanner from Amazon for about $50.00. here is a video to show you how:

Here is the BCM replacement instructions. Check out the diagrams (below). Let us know what happens and please upload pictures or videos of the problem.
