Kia Troubleshooting Questions? Ask a Mechanic
This is usually caused by a defective turn signal flasher located under the dash on the drivers side. Please rate my service, i will continue to answer your questions, until you are completely satisfied.
If it was a fuse, no lights would work at all, yours work only they work fast, indicating an issue with the flasher not the relay or fuse.
Turn the key on, listen for the flasher noise in the dash, determine where it is located, and replace it, it can sometimes be taped to the wiring harness if it the original, or if it has been replaced in the past by a professional technician.
