I have a 2001 toyota echo, my radio and clock dont work. They stop working when i plugged in my gps into the cigarette lighter. This has not happen before, i always plug my gps into cigarette lighter to power my tom tom. How do I fix this? a blown fuse or something more serious?

All of those are controlled by or influenced the BCM. You need a good auto electrician with a pro grade scan tool to check the BCM and communication to and from it.

Check these two fuses. Fuse number 31 in fuse box location 4, if cigarette lighter, radio and clock. Else fuse number 5 in fuse box location 2, if only radio and clock and not cigarette lighter.

The fuses in the engine compartment are not the ones that run the internal electrical circuits. IF you go to autozone website you can make a free account and then put in the year, make and model and then look for the free repair guides.

Your radio does run off of the same fuse that powers the cigarette lighter and auxilliary power outlet. I would check the fuse again. It is a 15 Amp fuse located in the Driver's Side Junction Block which is behind the left kick panel. The fuse should be marked "Cig"

it is lable cig.radio.accessory.there should be a fuse bx under hood and in the car under dash glove box it will be inside the car fuse box.

Sounds like the hot wire grounded when it came out. Locate the fuse and replace the fuse for that and the radio and everything should come back on.

check the fuse for the cigarette lighter and the clock is on the same circuit I think,do you know what caused the problem in the first place,check to see if there is a piece of something metallic(gum wrapper,etc)in the bottom of the cigarette lighter that could possibly cause a short.

My 2001 Toyota Sequoia just lost all dash lights last night too. I've tried checking the fuses in the cabin, and none of them look blown. Did you ever get an answer to this problem?

The radio, lighter and clock are controlled by 2 fuses:
The 15 Amp CIG and the 15 amp DOME, under the dash, driver side, for a USA car.

There are three (3) fuses involved here. The one that is most likely the culprit is the 15A one in the fuse box under the hood, near the battery. Check the underhood fuse box, replace any blown fuses.

The other two fuses (also 15A) are in the interior fuse box, probably left side kick panel.
