I have a 2020 Ford Explorer that has had intermittent issues with the passenger side losing heat since aprox 11/18/2023. On Friday 2/16 we had snow begin falling at 7AM locally. I park in the GARAGE. 1/2 way to work, on a major highway, my passenger side began fogging up. The heat was all the way up and there was no way for me to aim my driver-side vents to the other side of the car. After 4-5 minutes, my passenger side was completely fogged up and 1/4-1/3 of the windshield was also completely fogged up. In the 15 minute drive, I could not see anything on the right side of my vehicle and almost missed my exit, hitting a curb and scraping my rim. This is a known issue as there are 2 bulletins out by the NHTSA for my SPECIFIC make, model and years.
