Sounds like something going on with the body control module. I can't help beyond what little bit I found. Sounds like there is a short somewhere or blow fuse/bad relay.

U1000 is a vehicle specific code primarily found on Chevrolet, GMC and Nissan vehicles. It refers to a "Class 2 communications failure." Generally, this code will precede an additional code that identifies the module or area of the failure. The second code may be generic or vehicle specific.
