Kia Troubleshooting Questions? Ask a Mechanic
Hi, if you turn the hazard switch on do both side turn signals flash normally?
Ok, so even if you turn the hazards on still only the right side works? I know the issue is with the left side but to narrow it down I have to ask some questions like this
Alright. After reviewing the wiring diagram, if both work normally with the hazard switch on that means that the bulbs and wiring are ok. It is also most likely safe to assume that the body control module is ok since the signal goes through that as well. Since you can see the left signal on the cluster dimly flashing and it is flashing erratically but the right side works I'm willing to bet you have a bad combination switch. The switch is probably not making good contact and thus causing it to flash erratically and make the light dim. The combination switch is the switch that you move to turn the turn signals on.
