First thing you need to check is the blower motor. If it's not spinning you will not get air. Check the fuse, if that's ok, check the blower itself to see if its jambed up. You could also have a restriction like a clogged cabin filter

The heater blower motor or the blower resister are probably what is bad.Find the blower motor, turn it on high speed with the key on and hit the blower motor with your hand or a small hammer.I fit starts to work replace it, if not the blower resister would be next to replace.
