Car I have replace my fuses on 94 Corolla DX , But it keeps blowing out the fuses for the Taillights & brakelight.

Get yourself a set of factory wiring diagrams,
otherwise your wasting your time

You have no idea what you working on, without

There is a short somewhere.I would check the taillights for a hot wire grounding out or smashed against metal.

1.Unplug your taillights at the sockets and the front running lights from sockets.
2. put in new fuse after unplugging taillights.
3 turn on taillights if fuse blows then the wiring is grounding out somewhere between the switch, fuse panel, and rear and or front parking lights.
4.If fuse does not blow then plug in one socket at a time keep rechecking fuse. when the fuse blows after plugging in a certain socket suspect that one to be bad and replace.

sounds like a fuse is out. Check your fuses.

there is a short somewhere.put a test light in place of the fuse.
the light will glow bright.when the short is removed,the light will go dim

tray using 30 amp fuses.

That leaves only a couple things that may be the problem.

1 the break switch could have a short in it, or going bad. it is located on the break pedal its self, get on the floor and push it in and you can hear it click, some times they go bad.

2 the other is bad ground or a positiave ground, meaning a wire is loose on the ground side, or there is a bare wire on teh positiave side touching the metal.

3 if the connections on the light sockets thereselves, it will cause the same thing.

bottol line is your dealling with a short of some kind, and some times they can be a bear to find,

Good luck and i hope this helps a bit

take out the 2 phillips screws that hold in the cluster.there are some bulbs in the back of it,look and see that they are all ok.
the tail lights operate on a separate circuit,but the headlight switch could be bad, as it operates both of those sets of lights in the park and lights on settings.check all the fuses and relays in the fuse box under the hood and lower left kick panel

check the earth wire and fuse for your taillights

first off check your fuses if you hit hte socket just right in the rear it will blow the head light fuses .hope this helps contact me via e-mail if fuses are good so i can farther assist you
