I've found a lot of posts regarding this issue, but still haven't found one that led to the root cause. My 2014 Dodge Journeys windows fog up bad when the heater is on full blast during the winter months. I've replaced the cabin filter, verified two of the four actuators were working. The didn't check the ones that controlled individual sides, because I didn't think this coyld cause the problem bit could be wrong. That and it's a HUGE PITA to access these actuators unless you have very tiny hands and can contort yourself to reach the screws holding them on. My next step is to check the AC drain tube to see if it's clogged, but was hoping someone out there has a better idea of what's going on with this, and maybe had success at correcting their similar issues. AC compressor is working, hot air out of both sides, and when switched it blows down to your feet. Very frustrating, and unsafe to drive in the winter. Any help would be greatly appreciated.
