Question about 2004 Toyota Corolla
When I turn on the right or left turn light on it blows the fuse when I stop and shuts my car off.
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 alldata.com 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.
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.
this the red fuse below is GAUGE. the module on the right is the Flasher module.

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.
