thanks Lemans64, I checked power a few places and even swapped the new LED bulb for the indicator with a regular bulb just in case that was making it weird.
But I found the issue: when I lowered/wedged the steering column down so that I could re-install the cluster with the new upper switches (speaker and power antenna, which made it VERY hard to get it lined up/in there without crunching anything), I must have pinched the column wiring harness to the turn signal switch. Three wires look rough, so I'll be repairing/soldering/shrinkwrapping them, I do NOT want to try to replace the whole switch/harness right now (switch is all working fine, just the wires are the problem).
Onward!
