    2021 international lt. Climate control was working fine until just a few days ago. The cab still blows great, but nothing out of the bunk. I looked on the fuse diagram under the dash cover but there is nothing specific about "bunk hvac" I am hoping it could be just a fuse but I don't want to start pulling fuses willy-nilly.

    I would guess that you’re looking in the wrong place for the fuse. There has to be a fuse block in the bunk area.

    Going to look in side box. I believe there's one back there.

    Could be the bunk fan itself went out. If you find the fuse and it is intact, take a lead (light) tester to the connector for the fan. If all speeds light up but at different brightness, then the fan went out. You can also take a multimeter to each each lead for each speed, too.

    if you have an esbar heater, the fuses are under the bunk. easiest access it under the passenger side luggage compartment if I remember right.
