The transistor that drives the various levels of the blower motor is shot. It is shorted internally. This part is around $100 at your dealer. unless you had a bad relay and some used car dealer just jumped the relay with a wire. not saying this ever happened to me though...

Where is the blower motor resistor on a 2003 Jeep Grand Cherokee?

The blower motor resistor block is located on the underside of the HVAC housing (Heater Box) next to the blower motor. The blower motor is located at the right side of the dashboard. You can access the blower motor resistor block from under the dashboard. A Word of Caution! Stay clear of the blower motor resistor block heat sink - It could be Hot. Incidentally, I have read about people working on their dashboards and setting off the airbag. It is a good thing to disconnect the negative battery cable from the battery and make sure that it can not touch the battery post. Wait at least a couple of minutes for the airbag system to discharge.
