I have a 2019 29VE - so not identical, but maybe similar. The air coming out of my front vents is very low volume, so what you have may be "normal", but having said that, several of my vents have a very well disguised "On/Off" mode. If you look into all of your vents, you may see a black plastic circular control on one end of the vent that works to open or close your vents - make sure they are open. As I said, not all my vents have this control, so it's possible you won't have it on any of them.
