Have tried searching corner light/signal lights. Everyone seems to have a bad relay or bad bulb since 80% of the posts are "I don't know what happened, but my signal lights blink frickin fast!"

Buuuuuuuut, I've got a question guys,

My left side signal light is uhh..let me explain

When you switch the lights onto the 1st click, it's supposed to light up the signal/corner lights and tail lights, etc. Well, it lights up the front right side signal light, but the front left side doesn't light up. But when signaling left, it will light up.

Do I have to replace the bulb? Fuse? Wiring?
