Tail + License Plate lights out

[S0ULphIRE]

Gday all!

My Yaris' tail lights and license plate lights have stopped working all at the same time. I took it in to a mechanic who told me my indicator stalk switch was broken and quoted me $500 to repair

I'm not *completely* useless around cars :p so I thought I'd take a crack instead.

I took off the steering column cover and tested the indicator stalk's brass connectors (pic attached) with a multimeter. Every single connector registers ~12.5 volts, except the one that powers the tail light circuit.

Turning the stalk to "on" then "lights", I can see the brass connectors clicking down as they're supposed to, so the indicator stalk itself would seem functional to me?

I'm not too sure what my next step should be any advice would be greatly appreciated!

Hey Mods - could you please allow my post? I think it was auto-moderated when I added the image link. Thank you!
