Technical Rear fog light

[antonio500]

Dear folks
Thanks to be part of this forum.

I bought some days ago a Fiat 500 twinair 2011 pop.
Just now i realised that my rear fog light doesn't work.
I am testing it with road lights on.
No sign of it on cluster, and no light.
I checked bulb and is ok.
Can be button, but is not a function with so use. Other 2 buttons are OK.

If someone can help me i am grateful.
Antonio

Have you checked the fuse? No idea which one but should have a fuse card

Does the light come on, on the dashboard to say its on?

I have checked all the fuse on external and internal boxes, all ok.
Car does not have front fog lights, no fuse F30 neither relay.
Looks like rear fog light use another fuse. I do not find information, I guess that uses low beam light circuit.

No, nothing.
Looks like the problem is before switch (including or not it). I am waiting to get courage to take out dashboard to get switch bar and test it. Does not make sense a switch without use to be broken, but can be.
I do not know what is the source of the switch, if is from low beam directly or somewhere else.

Problem solved.

Solution for someone with the same problem:
I had to take out switch bar.
Making some pressure on conector starts to work.
Then, could be a problem on the cable conector or on the bar.
I put some jump wires between and mainipulating it was easy to identify what side was the problem. It was on the pins of the bar.
Dismantled and redo welding on pcb of the bar.
It's like new.
