Recently I noticed that my left turn signal has not been working properly. The issue was noticed after using the car to jump start another car :/, which may have led to the issue or it may have started shortly before that without my noticing.

When the left turn signal or flashers are activated, both the rear and front turn signals illuminate only one time and then stay off. The lights don't appear to be dim or flicker during the flash.

Meanwhile, the side marker and the arrow on the dash both flash 100% normally.

I tried to look at the fuse diagram, but didn't seem to find one for indicators, so I'm guessing there is not a fuse.

Anyone with a similar issue or advice, please advise. Thank you.
