Okay, I've looked on search.
Here's the deal: I drive the jeep and turn on the heater. It runs just fine and no issues with idle or overheating.
When I stop, the Electric fan keeps running.
I have to unplug it and plug it back in everytime I drive it.
Any reason why this is happening?

The aux is fan is energized when:
The engine temp reaches 213 deg. F.
The A/C or Defrost mode is selected.
Power comes from the Aux Fan Relay. The PCM completes the ground path for the relay when either of the above conditions is met.
Try tapping on the relay when the engine is off and the fan is running. This may free the contacts if they are sticking.
