[QUOTE="Edbert, post: 1385231, member: 28577"] Need to update... When I left work I checked and my truck has been on fresh (not recirculate) for a while, maybe forever since I never really paid attention, I just adjusted the temp via automatic. In other words, being on fresh will not resolve the problem, at least in the 100+ degree days with 55-75% humidity. But then I got to thinking (uh oh!)... Having the AC on is a form of dehumidifier. My nest thermostat can run the AC to reduce the humidity in the house, and if you turn on the windshield defogger it kicks in the compressor even with the heat on. With that...why wouldn't having the AC blasting with recirculation ON would it not seriously reduce the humidity inside the cab in a 45 minute drive? My guess is yes it does reduce humidity while running, but the coldness of the internal components is so high (low?) that it overcompensates for the cabin air being dried, and sitting there overnight allows time for moisture to seep in and collect.
