ac/heater wont blow any air out
 

i tried to turn on my ac (dont have one tho just tried to see if itll blow air out) or heater and nothing will blow out. i bought the car like this so i dont what it could be. i just need the heater to work for now since its a bit chilly but will also like to install the ac stuff.. but for now anyone know how i can get the heater/blower to work? its a 89 s13 btw

I've got the same problem on my S14, I'm not sure they're setup the same way but I did a little digging and some have said it's either the motor itself is shot, or the resistor. The resistor is the cheaper of the two so I would start there.
