Yes i replaced the dessicant sack bag tube thats mounted to the condenser when i replaced the compressor, not mounted to the evap core that somebody mentioned. Its PITA, think i would rather replace the whole condenser if it came with one installed allready. Im pretty sure these trucks use PAG. Not sure how relateable to POE they are. I use POE alot on refrigeration systems for walmarts. Im almost positive that all the blend doors work. You can feel the air flow change with the desired selection. The temp blend door changes with a change of temp setting. Assuming its working inside the box. I did the filter kit a few years ago. Right after i got a new evap core. The only door im curious about is the recirculation door. I watched it, as soon as i turn the key on, with the ac completely off or on, the door moves toward the fire wall. I can push the recirc button and the door doesnt move. Turn the key off and the door moves back away from the firewall. I get the same temp and airflow out of all vents. I think all the doors are good, just questionable about the recirc door. The dessicant bag could be the issue, i just had a hell of a time replacing it last time. I may have to look into that humidity sensor also. I wasnt aware of it or how it affects the operation.
