Dome light flashing with turn signals
When I use my turn signals it flashes the dome and dash lights and all the outside lights light up like the parking lights are on I have replaced the signal module, fuse box and turn signal switch
Kia uses a diode hiding behind the drivers kick panel, usually wrapped up with foam tape possibly taped to the wire harness, you can buy this part that you have not yet replaced, Kia should carry it in stock, have seen it several times for dome light issues. Ground wiring is also an issue. Good luck.
