Left Turn Signal Not working but the Right does. - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Something weird happened the other day, I was trying to turn left and my turn signal wasnt working properly ( it would go on and then turn off even though the Switch/Stalk was pushed down to engage the left turn signal). I Pulled off the road and tried my signals again and the same thing happened. Would go on and then off and stay off even though the switch/Stalk was engaged. When pushed up to engage the right turn signal, it works perfectly fine. I have a 2013 Brz. Only mods are the 2017 headlight swap and the valenti revo tail lights. Any Help or Advice would help!

I assume the bulbs all have their filaments still?

Yeah, they do. I figured it out and found out it was a bad relay. switched it out for a new one and it works perfectly now.
