i need help with my blower motor.

i gotta '93 del sol si. just bought a new blower motor for it. before my heat control 1 through 3 didn't work. now the whole thing won't work. it's not the fuse too. took out the old blower motor..and when i plugged in the new one. it won't work. i dont know what's wrong. it might be my blower motor resistor. if i replace that too..will it work then? can anyone help me get this thing to work? it's winter and it's cold. i have no heat! please.

you have a multimeter?
