    Check your sleeper wiring plugs under the boot on passenger side.
    They're are 3 plugs the big long one may have melted inside of plug or wires may have melted from rubbing on cab.
    Most likely the big RED wire on the bottom shorted out.
    Some trucks have fuse box under bunk and many DO NOT.
