I have a 2016 HR-V new to us. This is the first winter season. We are having a problem with the windows fogging up. The defrost works, how ever when we put it on def/floor it fogs. It this coming in these vehicles

 

welcome to the forum our 16 HR-V does not do this, but were in ca so not as cold. take the HR-V back to the dealer and have them fix it, write down all info, outside temp and what happens on the inside with def/floor is selected.
