2014 1500 Express crew cab with stock Uconnect 5.0 with the puck antenna. XM won't stay programed to my account. After a refresh program comes up in radio and then it goes back to the apply for a account screen. Went around the barn with XM they say it's the Satellite antenna control module. Also can't connect blue tooth devices to the radio either. When i got the truck(used) I was getting water under the rear seat. Replacing the seal around the third brake light fixed the problem, but water was getting in.

1. Any one else had this problem?
2. Anybody know where the Antenna control module module is located? Can't find a diagram anywhere.
