That means one of the loads on the fuse is shorted.
what you are missing is a real schmatic of the car.
why not read that first.
then pull all loads on that fuse 1 by 1,
or put them back 1 by 1, (better) to see which load blows that fuse.
no engine stated, there are like 5,... and wiring varies by that. has that, (fast)
or so does suzukipitstop. the real FSM it is.
ive posted both links 100 + times here.
IGN2 shorts. ill look for you. .....

first off , does fuse blow key on only
or only cranking engine??????

that fuse IGN2, runs fuse 5,6,7,8
so pull those and see if the short goes away.
if it blows only cranking the starter, then that is what is shorted,
the starter key line.
if how ever (im reading the real schmatic) the fuse blows only keyon.
then its is 5,6,7,8 is shorted. loads to one of those 4.
so pull them.
F5- not used
F6- a/c , defrog, pwer windows, headlights and DRL
F7- blower and A/C
F8- mirror.

once we know the Fx that blows above.
we then can start removing those loads.
that is how shorts are found , (unless you have the schematic like I have and the amp clamp meter, so i can see what load is shorted
the easy way ,there is no other way ,but to pull loads on the Failing branch.)

end sorts 101.

Probably your compressor for the air suspension. You can put a 12 volt light bulb in the circuit in place of the fuse while you diagnose the problem.

Here's the circuit.

2b94f90.gif Inspection and Verification

  1. Verify the vehicle owner's original concern by operating the vehicle to duplicate the condition.
  1. Inspect to determine if one of the following mechanical or electrical concerns apply:

    Mechanical Electrical
    • Shock absorber failure
    • Leak from air line(s)
    • Leak from air spring(s)
    • Ruptured air spring(s)
    • Height sensor damaged
    • Height sensor off ball studs
    · Open Fuses:
    • Town Car
      • Power Distribution Box Fuse U (30A MAXI)
      • Instrument Panel Fuse Panel Number 1 (15A)
    • Crown Victoria/Grand Marquis
      • Power Distribution Box Fuse AIR SUSPN PUMP (30A MAXI)
      • Instrument Panel Fuse Panel Number 1 (15A)
    • Loose Connectors
    • Corroded Connectors

You need a dealer tester for this check

AUTO TEST DIAGNOSTICS At the beginning of the automatic portion of the test, the control module checks for defective control module (DTC 70), for unstable battery voltage (DTC 80), then for shorted or open conditions that would create DTCs 39 through 46, and 68 through 71. If shorts or opens are detected, the automatic portion of the test is ended and a DTC 13 (Auto Test Failed) will be displayed on the SUPER STAR II tester. If no shorts or opens are detected, the automatic portion of the test continues. The control module attempts to raise and lower the vehicle to verify that all three air suspension height sensor states (trim, high, and low) can be reached. A properly functioning vehicle will be at trim height at the end of the Auto Test. If all three states are not reached, the Auto Test will end and again a DTC 13 will be displayed. A DTC 12 will be displayed at the end of the Auto Test only if everything checked to this point is functional. After the DTC 12 (or DTC 13) is displayed, the control module is ready to check for manual inputs. The manual inputs check the steering sensor and the door courtesy lamp switch circuits. During the manual test, the module continually monitors the door Circuit 159 or 24 and the steering sensor Circuits 633 and 634 Town Car, Circuits 834 and 835 Crown Victoria/Grand Marquis for activity. To pass the manual test the control module must detect that all four doors have been opened and closed, and that the steering wheel has been turned at least 1/4 turn in each direction. After the manual test, the STAR tester button must be toggled, or the control module will continue to monitor the manual test inputs indefinitely. Either a DTC 11 (Air Suspension OK) or other DTCs will be displayed at this time. After the Auto/Manual tests, the DTCs will be displayed automatically. Each DTC detected will be displayed for about 15 seconds. The code display will continue until all DTCs have been displayed. The display will repeat the DTC until the STAR test button is released (up). After all DTCs are written down, the pressed tester button may be released. DO NOT disconnect or turn OFF the tester. The tester is ready to enter the Functional Test.

SOURCE: I have a 2002 Ford F150 Supercrew. Fuse 15 keeps

I had the same problem on my 2001 ford 150 supercrew. My cruise control went out first, then a couple months later I could not put my truck in gear and the windows wouldn't work. Then the #15 fuse (5 amp) kept blowing. One day when I went to work the truck caught fire. The problem was the speed control module. It was under a recall. I took it to ford and since I did not take it to them for the recall they only covered the parts that was initially in the recall. I had to buy the other parts.

SOURCE: ignition fuse keeps blowing when i turn the key

It MUST be the starter relay coil - or the power wire that feeds it. Likely a short in the relay coil (AKA starter selenoid).

canada or USA, (diffr. laws, different wiring, even DRL up there)
station wagon or NOT?
THE TURNS FUSE BLEW OUT. 2nd time, 3rd,,,?????

ive answered Forenza blinks here, many times.

ill now answer by guessing USA non stationwagon and no DRL.
dash box fuse 4 kills blinkers

EF1 (engine fuse) 1 good?
dash fuse 14 and EF1 can kills emerg. flasher

so of Emergancy flash lamps blows fuse 14,(smaller of 2)
then the blinkers are in fact shorted.
does it?
if yes, then find out which side blows the fuse 3.
turns left blow or turns right blows.
so if say turns right blows, F4 fuse.
if true ?remove all bulbs front rear right bulbs.
does the fuse hold now,(means not blown)
then buy new lamps there. problem solved
bulbs can in fact short.
not just blow open.
Tell the full story and all this gets easy.
For sure emergency flash,

I have a 2006 Suzuki Forenza and my horn will not blow. Tried replacing fuse and the horn didn't sound at all, just blew the brand new fuse. Any help would be great!

its shorted, that line, the fuse blew saving you a nice fire.
are you using the correct fuel shown in you operators guide, see index , fuses.

do not mess under dash until you defeat those air bags, they can kill you. (break a neck easy) the schmatic is here.

official FSM
$4 cost, dirt cheap.

first look at the actual horn, see damage there, it or the plug.
pull its plug and safe off (means tape it) and see if fuse blows yet?
always work the simple side first, not air bag side,or the
air bag clock spring, inside, steering last.

its either path A shorted, (most likely but fate wins)
or Path B, shorted relay coil.
if horn unplugged, fixes blowing fuse, the horn is bad.
easy huh?

reset , i love that word, it's great new wave name for the computer
age. "all things get fixed by pushing a button."
nah, not even close.
  1. if the blower fan does not blow, the blower fuse is blown , check all fuses. or the fuse named that.
  2. the engine coolant must reach 180F or more, and hold there, or there will be no heat. (or tiny)
  3. if the blower blows cold air, (above good) then the dampers for the heater core is closed, bad dampers or controls.
  4. The heater core can packup if you fail to to proper engine coolant (drain,backflushes an refills.
  5. number 2 above can fail if the engine thermostat is bad or missing.
tell more get more, answer #1 first.

Ignition Fuse keeps blowing

Hi Jeff , in what fuse box is this 10 amp ign. fuse located ? I am looking at a power distribution diagram and i see a IGN 3 10amp fuse located in the I/P fuse box ! Is this the fuse that blows ? I see where you replaced the 10 amp with a 30amp . That is never a good idea , you don't want to make your problems worst . Melt wiring harness , could start a fire . Do you know how to do electrical trouble shooting ? How to use a wiring diagram , power distribuition diagram ? That fuse is hot in the run , powers the rear Heat / A/C , automatic level relay, ESC - electronic suspension control module , rear wheel steering control module , Plus someother thing's depending which vehicle , Y91 - ULT . Your Taho doesn't have all this options . find the thing's that fuse powers , disconnect them one at a time till the problem goes away .
