Ok if I Understand Works Fine till You push brake pedal that means You have a wire corroded. when you cross a hot and ground you blow fuse so start at brake pedal switch make sure connection is good following wires to brake lights on rear of vehicle. making sure no bare wires. more than likely its a hot wire thats exposed to weather that protecive coating has erroded and is touching body. all the other post are possible but if you were having issue with the binkers it would blow just as soon as turned on thats why I say the brake wiring

No my answer, dont buy that $500 PCM yet.
the Gauge fuse , see bottom left, above. runs lots of things,
the FSM covers this, fully 100%
it runs the Flasher module, the ECM, the integration module (BCM like) that runs interior lighting and many things off the IM.
if the fuse only blows, while blinking , id inspect all 4 corner lamps
id check the wires there and then replace all 4 lamps. if you
dont know how to bench test a lamp. then just replace them.
Gauge , (funny huh) runs the Alternator, if it shorts, boom the Gauge fuse blows. as you can see finding a short is not easy,
you never said how soon it blows. so,,,,, if quicky, id run it
with no alt connected. rear plug IG Plug pulled. do so for no more
that about 15minutes, the battery will drain fast (no head lights please,or fans for heater, no electrical things on, flashers on for sure.)
there are 30 pages, to see all IG1 power feed wires.
i didnt try to find them all.
but that is my point, if you dont have the book or login
then all this is pure wild speculation and guessing.
I did this for a living, so ,know the ropes.
once I have this information, i then use my ammeter to find it.
see a area MASTER here, do that.

and chris.

in your case you know what fuse blows. (stated wrong)
and with that , fact i can attach my ammeter, and the pull
modules to find which one has the active short.
in the case if the blinker module is passing excessive current
I then drop off the lamps loads from the flasher module
if that shows that my short is gone then the lamps are shorted.
i can even measure all 4 lamp wire feed to read this short with my ammeter and my CB.
using this.
this the red fuse below is GAUGE. the module on the right is the Flasher module.

I am going to guess a short in the computer (PCI) or BCM Body Control Module. I had a Jeep Grand Cherokee that had a similar problem. Maybe turn signal switch itself.

    we need to have a better post here, lets try that, , did the fuse blow 3 times,y/n , the engine stalls? and will not restart until, I replace the Flasher fuse? what I do in this case, is not guess. I open the book called the FSM and read the page on the PCM and flasher to see if the flasher is related some how, first. Btw1, fuses only blow for a short circuit, preventing the electrical fire. so Ill do that for you now. Its a Toyota not a jeep. I then inspect the wiring for damage, or previous collision damage. to wiring. Im looking now, the IG1 power feed run the Flasher Module , i wish you had said the exact fuse blow, exact location in the box. the ECM (engine EFI) does use IG1 power feed. so if that blew, so was engine controls. too bad you didnt stated the exact fuses. did you blows the engine bay box fuse or , cab fues? that be a start. ok i looked in both boxes, and neither have a flasher fuse, ther is a hazard fuse. this is because this car , uses IG1 fuse power feed for the flasher module. and lamps. "UNIQUE" so guessing bad PCI or BCM( this car has neither ) and $500 parts, lets start by stating exactly what fuse, again. the below is the cab box,. the correct name for the Flasher relay , is "GAUGE" and is 10 amps. Did you know that $1 lamps can short out (not a guess) the can, and if they do , are 500 times cheaper than any ECM sold.

A flasher would not cause this problem, It's in the trun signal switch, it needs to be replaced

Sounds like the flasher unit to me. Normally the emergency flasher and turn signal are separate.

SOURCE: 2004 wrangler blinker problem

What other problem did you have before the signals quit? Something that stopped all functions from the signals has to be either a feed or ground IF the flasher is good. Signals feed. Hot wire from the flasher 1 and it should blink underload, but not with a test light or DVM. In other words using a test light the flasher wire should be powered steady. All the rest of the switch is switchable. You should also get a hot wire when the brake pedal is pushed. Check for power at the brake switch,key off.

How do I replace the flasher for a 2004 Hyundai Santa FE?

I have a 2004 Hyundai Santa Fe.By me the hazard and blinker lights would work sometimes then not work at all.The flasher is to the left of the fuse box, very hard to get to, you need to get on your knees, i had to pull out both blue relay switches from the bottom of the fuse box to get to it,don`t worry the blue relay switches can only go back in only one direction if it doesn`t line up, rotate the blue relay switches untill they line up then push in gently till they are snug , i took a flashlight and saw the flasher, there is a clip on top and on bottom of the flasher that need to be pressed to release it, i did one at a time because both of them are hard to squeeze at the same time,once the clips are released pull out the flasher it is a 3 prong flasher and can only be inserted one way, i also removed the dash panel there are 3 screws that hold it in place, pull on it but be careful there are clips holding it in place that can break.The rotate knob might hang loose after you pull the dash just make sure you put it back.The raised lettering goes to the right when inserting it,don`t get upset it will fall a few times you need both hands to reinsert it hope this helps Jay

Blinkers stopped working

Your F--150 has 2 flashers, emergency and turn signal. Both are mounted on the fuse block under the dash. The turn signal flasher is mounted on the front of the fuse panel, the emergency flasher is mounted on the rear of the fuse panel. so replace the turn signal flasher should solve the problem. Let me know how it goes.
