There are several common heater problems for a 1997 f150. A stopped up or leaking heater core, bad thermostat or clogged up blower fan housing all can cause heat problems.
You probably have malfunctioning blower fans. A blown fuse can cause your blower fans to malfunction. The heat and air conditioning cooling is not being forced into the passenger cabin.
If you have the heat on in the defrost position , the air conditioning compressor will cycle on and off to help dehumidify the air if the outside temperature is about 50 degrees Fahrenheit or warmer
That will all depend of the type of system being used. Heat in an A/C is generated by the compressor and the heat extracted from the air it is conditioning. Heat in a heater can come from fire (gas, oil, wood) or geothermic extraction from water under ground.
