Answer
Have the air conditioning system checked and charged if needed (most usually do every couple of years).  If that is not the problem, the problem has to be in the heater ducting under the dash, mainly the divertor door is not operating correctly and closing off the hot side of the system.  Only a Jeep service department can help you with this one and it is not cheap (pretty labor intensive).
