No power in the Sleeper

Hello all. I've been pulling my hair out trying to solve this problem, but no luck. So I figured id come to the experts. I have a 2014 Freightliner Cascadia 125, and I have no HVAC or dome lights in the sleeper. No blower, and the lights wont work from either the front or rear switches. I pulled the 4-way flasher switch and replaced it, checked all the wiring, and all the fuses. The switch is getting 12v on the red wire at the back of the switch in the sleeper, and the stereo mute works. The sleeper control button on the front AC controls comes on for a second when you push it, then goes off. I cant seem to find the LVD in this truck, so maybe its integrated into the SAM? I've read a couple of threads about this and no one ever posts what the solution was, so I'm hoping that maybe you guys can help me out.
