Good friends, I have a problem with my kia cerato / spectra 2008 and it is that the turn signal / turn signals on the right side have stopped working ... I already checked fuses, relays, bulbs and exchanged between them and it did not work .. searching the internet I found a case similar in which those on the left side failed ... it should be mentioned that it does not work or directional at the time of crossing or in emergency / caution light ... in the case I found mentions the user that there was an "isolated relay" and That was fixed by opening the cabin rifle, I disconnected it but I had the problem of not being able to remove these screws, can you tell me how to disassemble them completely? I did not force not to damage the component, any other suggestion regarding the failure is welcome ... Thank you
