no air coming from heater help!!!!

can anyone help me i have 95 lumina apv and i have no air whatsoever coming from my heater cold or hot ive changed the blower motor thinging it was that but no luck im not sure where to go from there can someone help me please!!!!!

before spending any more money check to see if you have current going to the blower

is the blower motor running and you're still not getting air? If so, you probably have a large buildup of crap on the evaporator near the heater core.

ok thanks guys it was the evaporator thank u for your help much appeciated.... thanks once again
