My left rear turn signal is stuck on (orange one). It does not flash - just a steady light. It stays on with everything off.. even with the keys out of the ignition. I tried switching bulbs and it’s the same story. It turns off when I use the right turn signal. I’m clueless.

I checked the bulb.. that’s not it lol. Maybe the turn signal relay?

Also, I’ve just noticed water with my battery. And even today, behind my rear passenger seat. Maybe that’s related.

Any reply’s are very appreciated! Thank you
