Hello, Welcome to Just Answer.
The relay that you have changed is the only relay for the indicators and the emergency flashers.
The system operate from two fuses. One for the indicators and one for the emergency flashers.
Fuse no 2 10A fuse is for the indicators.
Fuse no 17 10A fuse is for the emergency flashers.
I might just be a blown fuse but if you find that the fuses are good let me know and we can take it from there.
Thank you for the information. It would seem as the power does not get switch through to the lights.
I have some wiring diagrams that will help you trace the circuit. The emergency switch directs the power. When in the off position the switch for the directional indicators are on, when one switch the emergency flashers on it will switch the directional indicators off.
I have two diagrams one which if a very simple drawing of the circuit and one that is the same as in your car.
I hope you this will assist you should you need more information please do not hesitate to ask.
The indicator wiring are on the exterior light page.
