Hello, I have no rear AC while the truck is running or if I hit the no idle ac when I stop. I checked the wiring coming into the sleeper. I have power up to sleeper ac and to the sleeper fuse box on top of the blower motor. The switches on the dash don't change speed or temp. The box on the sleeper wall doesn't work either. I do have the idle ac switch light up. Still nothing from the sleeper. The cab ac works great. Suggestions?
