My heater only blows a little bit of hot air when the knob is turned to A/C? on 2003 Jeep Liberty

I dont know what the problem is. Im hoping its not the heating core :(

Try all fan speed settings. If the fan does not change for each setting then it is probably the blower motor resistor. Be sure fan is operating 1st.
