Blew a fuse that powers radio/clock/lighter in 2004 Toyota Corolla. Cannot find the fuse responsible. Where should I look? The box under the hood? or the Box under the steering wheel? Any idea what #fuse?

one under hood and one under dash

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.

try looking under the kick pannel on the passenger side (it's below the glove box behind the carpet cover thing) their are fuses behind it!

The fuse in postion 32 (15 Amp) in the box under the dash by the steering wheel also powers your cigarette lighter and radio also powers the clock. If only the clock is dead then it is not a fuse issue. This is a very common problem with the 96-05 Corolla clocks. The clocks are very prone to internal failure.

There is a bunch of useful info there. Drop me an email if you have questions, thanks!

fuses are located under the dash on the driver's side. you have to lay on your back to see the fuse box. its black about 1" x 6". have a flashlight handy. The fuse box lid has a fuse map on it.

mine did the same thing. the fusebox for that is under the steering wheel.

The fuse in postion 32 (15 Amp) in the box under the dash by the steering wheel also powers your cigarette lighter and radio also powers the clock.

The fuse you are looking for might be in the fuse box under the hood. I think on or about page 203 of the owners manual it will show the locations of the fuse boxes. The one under the dash is a little tricky. Just figure out what by looking at the pattern of the fuse lay out. You are looking for a 15 amp(blue) fuse I believe.

After you fix that I would recomend using the power outlet. I believe there are 2. One just in front of the shifter and the other in the center armrest storage box.

Pg. 250 of your 2006 Owner's Manual shows the location of the Fuse Boxes. There is one under your hood on the driver's side and the other is under the dash just to the left of steering wheel. Pg 272, will show you how to replace the fuses. Pg. 286-287 gives a diagram and description of each fuse and what part of the electrical system it enables. 

I blew a fuse while using my Cigarette lighter/power outlet to inflate my tires. It took out the power to the car stereo, the clock below it, and the two Cigarette lighter/power outlets. 

This portion of the electrical system correspondeds to the fuse in position 32 on pg. 287 of the manual. 

Your going to have to get on your back with a flashlight and open up the fuse box under the dash by the steering wheel. The lid of the fuse box shows the positions of the fuse and their amperage rating. Like I said, replace the fuse in postion 32 (15 Amp). There is a spare 15 Amp fuse in the fuse box under the hood (easy to get to, see the diagrams in the owner's manual). There is also a fuse puller tool next to the spare fuses. 


I hope you would be able to find the radio Fuse. 
Any further questions regarding replacement, feel free to contact me.

Thanks for using Fixya.

Please replace all your fuses. Some of the fuses are bad. This should fix it for you. Cheers.
