My left blinker works perfectly. On the right, there is no "click click click" and the dash arrow stays solid, and the far right taillight goes dark unless I cancel the signal. All 4 taillight bulbs are working, so it's not a bad bulb. Would this be the turn signal switch inside the column, or the turn signal relay in the dashboard? Or possibly a bad fuse? Something else I'm not thinking of?

I'm a bit stumped that one side works perfectly and the other side doesn't. Any help appreciated.

 

The tail light and the turn signals are 2 separate circuits and 2 separate filaments within the lamp. Just because the tail light works does not mean the other filament is good. Turn on the 4 ways and check the bulb that does not blink.

 

You have a bulb burned out. The turn signal circuit is designed so that when a bulb burns out, it will not flash and the indicator stays on solid. Find and replace the burned out bulb.

 

I'll be damned if my far right bulb isn't toast. Thank you to you both--I'm new to this '73 and am learning as I go.

 

Thanks for the help, and hello from Tulsa!

 

Your very welcome, perhaps we may run into each other at some time.
