Problem Solved!
Took the indicator stalk out (you don't even have to remove the steering wheel) and guess what. Small green wire had come disconnected. There are a pair of these wires coming off the stalk and when you signal they move slightly and this obviously broke the wire over time. There is a small tie wrap that is supposed to be a strain relief but there wasn't enough slack so I fixed this with a new tie wrap in a better location and re-soldered the wire.
Total cost of fix $0
Things are good again.
