Weak or uneven cooling from the vents can mean the expansion valve is not metering refrigerant properly. Before you replace it, rule out a refrigerant leak, a restricted line or a failing compressor, since any of them can weaken cooling as well; a shop can test the A/C pressures. The 2013-2023 Freightliner 122SD takes one valve.
