Nissan Altima: heater

my heater only worked on the highest setting,so i thought it was the heater
unit so i replaced it and it does the same thing,now it doesnt work at all,
its a 95 altima and how would i find out if the resistor is but or if it has
one at all?

thanks i found one at the junk yard,and now it works great thanks for you
help.
