    The sleeper will have its own expansion valve, you need to check that and make sure it’s working properly.

    No air flow from the vents? Or just not cold?

    check the ac lines under the cab. also check the drain tube. right rear corner. make sure the drain tube isnt stopped up. use your fingers to open the end of the rubber tube. you want it to drain like a hose. check to see if one ac line is hot too the touch and one is cold. this is with the ac on high. also check ac bunk filter on the box. after this is done. then its time to pay someone to put gauges on it. if the expansion valve is plugged. this will cause the problem also. but the first 3 things i would check is the lines and the rubber drain tube
