Good morning 52 and welcome to the forum.
There has to be a fuse someplace for that AC. Possibly under the hood or in the engine compartment. A fuse separate from the fuse panel inside the cab, if there is such a thing on a FreightLiner.
Like on the newer vehicles from about 1998 or 2000, they had a fuse/relay box in the engine compartment. And also a fuse panel inside the cab.
Might check that out and report back Your findings.

Welcome to TTS! Columbia CL120 with the Mercedes engine? we work on those a lot here at work! no power to the AC it's most likely a circuit breaker in the cab. that panel is located on the top passenger side if the dash. I might be able to get you a drawing from Freightliner if that will help you there is also a power distribution block on the drivers side of the firewall next to where the steering shaft goes into the cab if memory serves me right.
I have some contacts at our local Freightliner. send me the vin and I can try calling in a favor lol

something else to check is in the battery box. on ours here at work batteries are under the steps, there are a couple of breakers and power junctions in there, you might check the connections there also. other than that might check the pressure sensors on the ac lines, dryer and condenser.
