SOURCE: heater blowing cold air
squeeze the hoses to get any air bubbles out and refill coolant as necesary. are you sure you put thermostat in the right way? may be backwards. also may be your sensor.

Not an expert by any means, but i know my ranger.. I had a small leak at the top of my radiator that still cooled the engine but didnt have enough pressure to get to the heater. The heater hoses travel up over the engine and just were not gettin anything to my heater core. That or make sure the heater control valve is operating.

Temperature Control Blend Door Failure No Heat or no AC (dependes on
where door sticks)
all modern cars there is a tiny DC electric motor driven gear drive
that moves a plastic door that blends heated and cooled air from the
AC and the heater core, this is called (interestedly enough) the air
temperature control blend door actuator. The motor that moves this
door fails because the door starts sticking from warping, most common
complaint is no heat but it can be no AC as well. To replace these
parts (blend door and blend door actuator) you must remove the entire
dash from the car. Always have this problem confirmed by a dealer or
qualified repair shop as it is a very expensive repair.
Other causes of no heat in the cabin are engine thermostats that are stuck open (engine runs cold) or air bubbles in the cooling system.
