My HVAC unit on '03 Cadillac Escalade EXT doesn't work. What can be the problem?

I went to see my family which is about 150 miles away. On the way back, my heat stopped working. No matter what temperature I set on my unit, no air would come out of vents. I checked the fuses - they seemed OK. Is it a blower or something else and how do I check?

does some heat flow out of the vents when on the highway?

I believe so because it got pretty warm eventually even though it was around 30 outside. But I think it was flowing from the bottom vents though.
