2021 New mar New Air, dash air conditioner not working. Blowing warm. I have lots of Freon in the system according to the gauge I hooked up. Pulled fuse and replaced , not sure what else to do.
 
Welcome to RVForums.com @Gdoubleoo. Take a look at this thread:

 
Gdoubleoo - does the compressor clutch engage when you switch the ac on (even for just a second)?

Theere was a known issue the Eaton PDM (Power Distribution Module - many fuses and breakers) next to the chassis batteries 2019-2021 and Freightliner has replaced them under a recall.

Also- i had the actuator at the heat/ac transfer box in the front go bad, so it was always circulating hot engine coolant and the AC cannot overcome the heat.
