Thanks, that's a great help!
Again, it only fails in elevated humidity (and it doesn't have to be swampy, just damp air), and when it fails, both sides fail to cancel. And it hasn't happened for months, but even more rarely, the signal failed to actuate in both directions (and also failed to mechanically cancel when that happened). So it doesn't appear to be a mechanical failure, but an electrical one. I'll be checking all of the solder joints in the pod connectors and the circuit board to the turn signal switch, as well as all contacts.
I should mention that this car does something I've never experienced before: Anytime the ambient temperature is below about 45F, turning the wheel even slightly in either direction results in a horrible groaning sound, coming from directly behind the steering wheel itself, inside the collar that contains the ignition switch. It sounds like a door hinge in a haunted house, or an oar in an oarlock, and it's so loud, it probably can be heard outside the vehicle. Once the cabin temperature exceeds about 45F, it does not occur, ever. It's definitely in the column, just in front of the instrument pod, and not in another part of the steering downstream. I feel the vibration/binding, but no real extra steering effort.
I have a spare steering column from my 1992, and I've been waiting for a summer weekend when I can swap it out. The '92 column has cruise control, and I have everything swapped over for cruise control into the '93 except for the switches on the steering wheel. The reason I didn't do the swap yet is that I have to swap ignition cylinders, so that the car will be keyed the same, all off the same key. I expect this problem will go away, as it never happened with the '92.
