Bill, without seeing it in operation, it is a little hard to guess. Typically, with an LED conversion, the blinker unit in the dash doesn't work right because the bi-metallic strip needs a certain amount of current flow in order to get hot and kick on and off. Since all your other lights seem to be working normally, it doesn't sound like that's your problem. I would have to say there's got to be something wrong with the wire, socket, or bulb on that corner.
Is it 'permanently off' or 'permanently on' when you use the turn signals? If it's "off" then I would check brake operation too, and definitely make sure the bulb is the right one, socket is clean, etc. If it's "ON" then you have a somewhat more exotic wiring problem I'd say.
I smile a lot. It makes people wonder what I'm up to...
