nissan nv1500 cargo van ac stuck on defrost?

What is your question?

So I have a Nissan NV1500 cargo van for work and recently the AC stopped blowing out of the main vents, it seems to only blow out of the window defroster vents. It blows cool and hard out of the defroster but even when changing the mode nob it still only blows out of the defrosters. It doesnt have any weird noises or sounds to show there could be a leak at this point I'm stumped and don't have a ton of money to just take it somewhere what can I check that could be the problem and is this problem normal with Nissans?

What makes this problem better or worse?
