Kia Troubleshooting Questions? Ask a Mechanic
Hello. I have seen a similar problem when the flasher is going out. Have you tried to replace the flasher?
Have you had any other issues?
Ok, I have looked at the wiring diagram and there is not much in that circuit. I have attached the diagram. The only possible cause should be the flasher unit itself. Both the turn signals and the emergency flashers run through that and it is the only thing will cause the circuit to blink.
I hope this helps. It is possible that the replacement unit is also bad? Have you replaced the fuses and the bulbs? These are the only things in the circuit, so process of elimination is the only way to proceed.
