There could be a fusible link under the hood off the starter relay that is burnt out.

SOURCE: a/c heater fan no blow
sounds to me like the blower motor resistor, and if I'm not mistaken the resistor and the blower motor are located under the dash on the passengers side. the resistor should have a wiring connection and 2 screws attaching it to the blower case. The a/c and heater blower will not work if the resistor goes out. hope this helps you out a little. Best wishes.

OK...I have a 93 outside...one diagram I have shows an ignition module next to coil...but there is none on mine, (4.0 engine)
Two items to check are crank sensor and cam sensor inside distributor. Test procedure can be found in just about any manual including haynes.
You will need a decent volt/ohm meter to do testing. You can also check codes by turning ignition switch on/off three times, leaving it on the third time. Check engine will flash code #'s (ex: one flash, pause two flashes= the number twelve.then followed by a longer pause then another set of flashes etc.)

Check the wiring from the relay to the fan motor, and check the wiring from the fuse block. Basically check all wires that supply power to the fan motor, use a volt meter. Fan Relay (behind headlight, under battery) on the 2001 GC 4.0L are a piece of ****, I change mine almost yearly. The problem is their location, a high heat area prone to the elements. I understand that 2002 and newer, the location was changed and the problem solved. Relay might close the circuit when cold or at reasonable temps, but might open a circuit when it heats up, causing the problem.
