    At my 2015 Toyota prius c the dashboard direction green lights don't work.
    The other dashboard lights work.

    Outside yellow blinkers don't light up. Headlights do work.
    Could be a fuse...or...?
    Anybody can help??
    Thanks

    I did replace the the Hazard 10 fuse and I found out that there was no voltage with the switch contact on. When I replaced it with another one from the horn fuse of same value 10 the green dashboard lights started to flash but in the same time the yellow light for " check hybrid motor" lighted up.

    I didn't have the right fuse size and that's why I took out the horn one.

    After I bought and replaced the right size hazard 10 fuse nothing happened, nor even when I replaced it with a 2nd one from the same box I bought from Autozone.

    My question is: did this happen because I installed a generic fuse instead a Toyota genuine part??

    I don't know who to continue further the diagnostic. Should I buy a Toyota genuine fuse and replace it to see if it helps.??

    The brand of fuse does not matter as long as it is the same value (10 amp in this case) and fits the same.

    You can tell by looking at it if it’s blown or by using a meter.

    It’s not clear in your posts if any of these fuses were blown. That is critical information. We don’t know if you have checked the bulbs.

    It is also likely the combination meter (dashboard pc board) is controlling the flashing. It could have a fault.

    The electrical diagrams are on the TIS Toyota site that requires $25 for two day access. https://techinfo.toyota.com/techInfoPortal/appmanager/t3/ti?_pageLabel=ti_whats_tis&_nfpb=true

    Thanks, as I wrote previously, with the switch on there was no voltage value on the fuse mounted on.

    1.Also when I.checked the fuse resistance or continuity there was showing 0 ohms.
    I.will try to replace again the fuse with the horn fuse and check voltage reading with the switch on.

    2. You didn't answer my 2nd question about the " Check hybrid motor" dashboard sensor light when I switched fuses: I put the 10A horn fuse in the turn signal place and the turn signal fuse in the horn place. Does this has anything to.do with the wiring or ots just the computer module fooled diagnostic ??

    I checked the fuse with the voltage meter and there was 0 with the car switch on.
    Visually it doesn't look blown. What is important iss that when I replaced the turn signal fuse with the10 A horn fuse, all the turn. lights, hazard and dashboard green lights were working fine.
    The only thing I noticed was the "Check hybrid motor" yellow light was on.
    CAN U EXPPLAIN THAT?? ANY HINTS OR HUNCHES???

    Possible you put the fuse in a previously empty slot or there are other blown fuses
