Not familiar with this jeep, but it most probably has a blower motor resistor or controller. Most of the time this resistor or controller is faulty.

On the WJ its just mounted besides the blower motor, seen up from the passengers foot well. Maybe on the wrangler its the same. Not sure if it has just connectors, or that the wires have to be soldered. In the last case, take care to connect the wires correctly, otherwise the fan can rotate counter wise and will only produce noise and no air.
