If the car isn't blowing ANY heat, it is your heater coil, which is a definite shop repair. IT happened in my 96 Grand Am
 
Hey there Rob is right check for a hissssssing sound when pulled to the "vent" ..no sound at all.........its the vacuum hose just behind those knobs.Oh Oh you changed the blower and pulled the hose off by accident.
 
Check the fuse for the heater and change the cabin filter

Have you checked to see if the heater core is clogged? could be many things; an air lock, faulty control, no vacuum, broken cable, etc
