That fuse blowing saved the ensuing fire. that is its job, no fires.
that means, it has a dead short on that line,.

if you dont have an ammeter, and fuse circuit breaker adapter tool.
both cheap) you will play H3LL finding it.

so wana buy tools or guess. you can inspect that line for free.
looking for days. ????
the first thing to do is look at the schematic,
for fuse 3 (fuse 3 inside or outside fuse box.) there are 2 fuse 3s/
seen here for free

one fuse 3 is 30amps. runs the ignition switch (vast paths)
fuse 3 PDC. must not be that one.
the interiour box, is called FB, or junction box.
it has a #3 too. called FB

page 8w-11-4 see that page.
see all them loads.... all can short. or the wires.
its and ORANGE wire (USA colors)
ONE OF THOSE is shorted, or the path to it.
we use and ampclamp meter $45 to find this.
it tell which line is shorted and in which direction.
makes finding it easy,

matching size, i use a CB.
ATC fuse circuit breakers 10amp
this allows me to find the short, and not need a box of 100 fuses.
i have a 1 hour video that shows (no me, a school)
showing how to find shorts. (youtube)

if fuse size is ATC, get thermal breaker.
it auto resets. so you can just keep measuring current and see
it trip, over and over, and watch the meter.
while tracing the plath

is this the answer you want or a wild guess.?

SOURCE: Blows fuses when parking lights are turned on. Headlights work fine even running lights.

If it only happens when you turn the switchto the parking lights then it is most likely the swich that is the problem. Light swich failure appears to be a common fault with fords

You have two locations for the fuse box. One is either under the hood or behind the glove box. I would pull apart the glove box and take a look.

SOURCE: Jeep wrangler Fuse box

i had the same problem. i drive a 95 so im not sure if it differs from were the fuse box is. look righ above you pedals to your far left. it should be right there. also if you instruments went out it will be a 15 fuse. its a blue fuse. next my panel went out cuz of the wires on my transmission. if yor looking at your jeep at the front. the wires will be on your left. make sure they are not burned or anything. it will be right on the side of your tranny. mind got burned by the exaust so they were shorting. check that is and see if that is what is it. for a temp fix just put some electrical tap around the wires and you should be set for a wile. good luck

SOURCE: 1996 ford f150 blows the 10amp fuse going to the speed odometer.

I'm glad you found what was causing the fuse to blow. A wiring diagram is almost a must when troubleshooting electrical. you may be able to find that sensor at a pick-a-part or wrecking yard. Just be extreamly careful, it is very easy to set off the air bag. Make sure that all power is off before working around that area.

SOURCE: engine 1 fuse keeps blowing when you turn the key

Engine 1 fuse powers the computer and some sensors. I had this same problem on a 98 chevy van 3500 and found the wire going to one of the oxygen sensors had shorted out on the heat shield. Inspect the wires going to all of the oxygen sensors. On this van one of the oxygen sensors on the driverside the wire was laying on the heat shield which eventually rubbed through the wire and shorted it out blowing the fuse. Your short could be on a different sensor but check all of the oxygen sensors because the wire runs so close to the sharp heat shield.

you should scan the computer of your Jeep Wrangler to get a diagnosis of your electric or electronic problem. By the way, if it's a 2015 model, it should be on warranty?

Jeep fuse panel diagram

please post accurate symptoms
does the fan blow fast on high, is the first question.
sure going down road works that is the natural cowl vent doing that,
free air.
the controls for the fan are in the FSM covered 100%
ever consider looking there first?
see chapter called HVAC here.
then see wring, hvac, last chapter. TJ car.

ever heard of $10 voltmeter, for that grand sum all that work and guessing ends, and the hug costs.......
if the fan dont have 12vdc to it ,it can blow. fact.
so yours dont.

first would be a new blower fuSe for 10 cents

wiring index is page 19 /236 pdf page
and 8w42 is hvac. pdf page 103

page 105 pdf is yours.
all on one page, and a volt meter and bang the truth.
no guessing no fiddling around.
ask for help with Vmeter.

on high the motor is ground.
the other side ,needs 12vdc from the blower relay
both fuses must be hot (12v) both side or the relay will be dead.
easy huh?

Instrument Panel keeps blowing fuses

It isn't the ground; if you lost the ground, it wouldn't be blowing fuses-it wouldn't be doing anything.
There may be a short in the panel, or in the wiring to it. You will need to pull the instrument cluster out to investigate. If the wiring and connectors look good, probably need a new cluster.

I need a diagram for the under hood fuse box. More importantly the specific 20 amp fuse labeled F21. What is it for. I have a 1998 jeep wrangler 4.0 4wd.

Are you sure that this is for 20AMP, according with the repair manual, the position 20 in the Power Distribution Center if for Power Motor ABS Pump, and is 10AMP.

Verify it..

2000 jeep wrangler fuse keeps blowing?? What do I

That or the wiring to it is shorted at some point. Remove the connection at the center back of the socket and replace the fuse--if ok, replace or repair the socket. If still blows fuse, check the wire you removed for damage near any metal object.

1999 Jeep Cherokee Sport The fuse that handles power for the instrument panel, radio, remote key, interior lights, ... blows from time to time. When I insert a new one the new one immediately blows as...

Not sure but I advised you before!!
Any way last time!
You have to t/s the moment the fuse blows and elimate the systems (short) connected to that fuse, for sample, dis connect the interior light, install fuse, if it blows than it is NOT the interior light, keep going till you find the short!

Fuel ECU fuse keeps blowing (30 amp)

Your fuel pump is internally binding and causing the fuse to blow. Change the pump (and filter while you're back there.)
