Fog Lights No Longer Work???

So they do use different current afterall? It's still kind of interesting how relays are used here, whereas the proper switch eliminates the need for it...

CTScott, any hunches on the initial problem? It remains unsolved. Although unimportant now, I hate not being able to figure things out

The same fuse feeds the coil and the contacts, but the current switched to one versus the other is significant.

As for the initial problem, I would suspect a bad ground connection. All of the lighting circuits on the Yaris are switched on the ground leg, so to complete the circuit you have to ground it.
