Tail lights are not working

Fuse?

 

The tail lights often have a common ground for both bulbs.
First check the bulbs.
Then check the ground.
If you don't know how to do that, find a Toyota shop.

 

That doesn't mean they can't fail.

 

I'm going to add to this thread. since the same thing just happened to me with my 2012 C4. I was driving home last night and a co-worker happened to be behind me. He called me to tell me that my tail lights were both out. Brake lights work, turn signals work. I was hoping it was just a fuse (BTW, what a pain in the...back...to get to that fuse box) but the fuse is fine. Plus, the fog lights and other things on that fuse all work.

As it happens, I just replaced a tail light bulb a couple of weeks ago. Seems like it would be a weird coincidence for both bulbs to have now failed. Could that have anything to do with it? If not, what are my next options? Thanks.

-edit-

Oops. Now that I think about it, I'm pretty sure it was a turn signal bulb i replaced.

 

As was covered in this thread......first be sure it wasn't in the DRL position.
Buy a multi-meter and check the voltages and grounds.
Take it to a shop. Hopefully the problem and the fix will be simple and inexpensive.
And if not, you probably couldn't have done it yourself anyway.

 

No, it was definitely in full "lights on" position. But it was a simple fix. I replaced both tail light bulbs and all's well. Funny thing is when I first discovered the problem, I was hoping it was just a fuse. But after going through all the contortions required to check the fuse, now I'm grateful it was the bulbs, as they're a lot easier to replace.

 

Just found this forum, love it.

I’m having pretty much the same problem as described here. I’ve changed both bulbs, hasn’t helped. Doesn’t seem to be the fuse, as all the other lights that are meant to on the same circuit are working (park lights, license plate light). I guess I’ll take it to an autoelectrician, will try to remember to post here what the issue is.

 

Both of my tail lights went out. Fuse #30 under the steering column / dash was blown. Replaced. Blew again.

turns out, the wiring on the DRL light in the front (right, but could happen on the left) was fried and shorted, taking out the fuse.

here’s what I think happened: the front DRL lamp housings got corroded (see pic). Corrosion causes connector/wires to get hot. Insulation melts. Wires touch. Fuse blows. All DRL/tail lights go out.

 

Sorry. More pix.
