Yamaha Turn Signal not working
 

I have a problem...was installing new led Mirrors in 2013 Yamaha (gas)... now .. my left turn signal, turns on with the key as if were hooked up to running lights and will not flash even if I turn on signals..
( I did see a nick in the existing hot wire that could have touched the ground) Right side works fine...... I thought it could be the turn signal module but y would the signal lights work go on with the key and also other side works fine. I have also disconnected all the wires but it did not correct the issue... Hope you can help...
Thanks Ron
