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.)

SOURCE: radiator fan not working replaced relay,temp

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.

Blowing fuses to the auto shutoff


Well that relay powers several components, including the fuel pump relay, ECM, and injectors.
Have you narrowed down which circuit has the short to ground ?

Auto shut off fuse keeps blowing,why?


The short answer is you have something pulling too much current in the circuit.
The long answer is that circuit powers several other relays, so you may need a wiring diagram to know what to check.

Auto shut down from hitting a bump- no fuel pump or ignition - voltage gauge not working


You have a ASD relay (Auto shut down relay) this is not a safety device you basically knock something loose.Turn the key on do you hear the fuel pump go on. If you dont check the fuses for a open condition and fusable link that are on the battery with key on wiggle battery negative terminal especially at the engine block and the frame ,same with the Positive part of the battery terminal .

Jeep grand cherokee drives then stops -no power to anything


More than likely you probably have a faulty relay switch. Under the hood you will find a relay box with a removable top. Check the relay that runs the ignition fuel pump. It heats up and then breaks the electrical current and disables the vehicles ignition or fuel system and the vehicle shuts down until the relay cools and reengages.

98 grand cherokee asd relay blowing fuse


The fuse it doing it's job, you have a short ( Wire that is connected to a ground, that draws too much power )

If you have an electrical schematic ( Repair manual ) find out which wires are connected to that fuse and check them for any chaffing, cuts, unnesassary twists, or corrosion.

If you have a ohm-meter, isolate the system ( by disconnecting the fuse, and other connections. Then check for any resistance on wires that should not be connected ( because you disconnected them ) by having one Lead on the wire's connector and the other meter-lead on your car's frame. A good wire will not have continuity if it is isolated.

Chk the battery ground cable, Remove and clean. Then chk your charging system at the battery. Should charge between 13.6 and 14.2v If it is charging above 14.2 your alt is barely charging, The further below 13.6 the more amps the alt is putting out. Make sure you battery has adequate water in it. A battery will rejuvinate itself after it has gone dead after sitting awhile,but only enough to last a few minutes. Turning on you headlights would kill it right then.

Check for any loose or frayed wires either near the fuse box or further down the line. If this does not apply then I would put a fuse that takes a little more amps to blow.
