Yaris XP rear fog light issue

[bubu]

I have a XP9 from 2007 Europe version.
back light fog does not come up
bulb is ok
fuse is ok
front fog light works fine
light indicator for front light comes up for back not.

The rear fog is fed by the 7.5A RR FOG fuse.

The rear fog switch either directly feeds the rear fog light or indirectly feeds it via the Rear Fog Light Relay. If your car has the relay it will be located on the bottom right side of the under-dash fuse panel.

The indicator is driven directly off the feed to the bulb, so if it is not on neither will the light be.

I would check for the presence of the relay on your car. If it is there, check to see if you hear it click when the headlights are on and you turn the rear fog on.

Yes. The indicator is fed by the power to the bulb.

If you look at the under dash fuse panel you will see many connectors on the face of it and some relays at the bottom. Attached to the right side of it there is one connector and one or two relay sockets below the connector. If your car uses the rear fog relay there will be two and the bottom one will be the rear fog relay.

I have a missing relay but I am not sure that it should be there ... and recently they fixed the mirror switch in that area ...do you have a picture because I am having trouble to realize which is this exact relay...
