07 Yaris - Signals don't work, where's the fuse?

7. Passenger set belt warning light

8. AT Shift lock ECU

9. Flasher relay


You should actually be able to isolate it to one of those functions by trying each one separately and seeing with which one it pops again.

So, I think I've narrowed it down to the signals, possibly just the right turn signal. I didn't get a chance to test the left turn because I didn't want to risk blowing the fuse again as I'm almost out of spare fuses by the time I noticed. When I signal, it flickers and eventually it broke and when I put it into park, it stays in park...etc.

Question is: I don't know much about cars beyond the very basics. I looked up a few similar situations via google and found it may be bad wires or a signal switch issue. If I took it in, what should I say and how much should I expect to pay to have it fixed? What's too much and/or a rip off?

Thanks in advance.

In 30 years of driving I have never paid someone to work on my car, so I couldn't guess what they would hit you.

It could be a damaged wire, but more likely either the switch or the flasher module is to blame. For parts, Toyota would charge you about $110 for the headlight switch or $45 for the flasher module.

The flasher module is easy to replace yourself, as it is the blue chunk mounted to the front of the under-dash fuse panel. Replacing the headlight switch is a bit more involved as you have to remove the airbag and steering wheel.

One other quick and dirty test would be to swap the turn signal bulbs on that side with the ones from the other side.
