The resistor enables the heater blower motor to change the speed of the fan. Without this part you will not be able to change the speed of the airflow from the blower motor. It is also possible that the heater motor blower may not work at all. If the resistor has gone bad, it is likely that the fan will work only on the highest speed.
Why does my AC blow cold then blow warm?
The moisture can freeze into ice crystals right at the orifice tube or expansion valve, clogging it and stopping the flow. The symptom appears as: blows cold, then warm. If you shut off turn on the heat for a while, that’ll melt the ice crystals and the system will start cooling again. But it will still freeze up.
