At times maybe once every few months the clicking stops for a day then starts back. Turn signal lights on dash work and outside when this happens.

Any ideas other than replacing BCM.

 

There's a fuse bank located in the lower left kick panel and one controls all your electrical features. That might be worth looking into and replacing.

 

I just now went and tapped on the bcm and it started working. Probably going to an issues from time time.

 

Tapped on BCM? Then it sounds like it might be going out, strange how nothing else is acting up but a turn signal. I was about to replace mine when I was having an issue with the rear hatch opening itself while driving or idling, was just a bad wire from license plate harness.
