I'm going to send you some diagrams. When I first read the post I thought the brake lights had gone out at the same time. Thus thinking into the ground. I don't know that the problems are related but would go after them one at a time. IF they are related, the common denominator appears to be the BCM. Now if that is the problem, it may just need to be flashed.
But things I would start checking are still the grounds to start with.
G300 is under the driver's seat.
G201 is near the glove box lamp switch.
Check your email for the diagrams shortly.
