My heater stopped working a couple of weeks ago.

First, the fan would only work on the highest setting. It was suggested that I change the heater resistor inside the glove compartment. I did, and now all of the fan settings work.

However, the heat will blow absolutely cold until the temperature gauge reaches halfway at which point, the heat will be fully hot, but as soon as the temperature gauge falls below half, the air goes immediately to cold.

Why is this?

Low on coolant check your antifreeze and check for leaks
not a bad idea to replace the thermostat too
