I’m going to be pulling my glove box today to determine if my foam hose is rotted out or fallen off and replace if necessary. In addition to this issue I have almost no heat going to the foot wells on either side. The Push Button Unit seems to be working as there is a corresponding change in air flow volume from the defrost area and the upper side vents when when I change selections. FYI the center vents do not function correctly with air conditioning setting. I believe the pod controlling this is broken as it stopped working last year. Any thoughts about the no heat in the foot wells? Thanks, Mike
