Today I went out to the car, started it up and the turn signals are working. I checked fuse #4 as mentioned in a forum search, only to find that fuse #4 is for the heated mirrors only, so that was a little misdirected.
Surprisingly, there is no listing for bulbs or turn signals anywhere on the fuse labels, but there is a fuse for the four-way-hazards. Standing there not really knowing where to go next, I decided to remove and re-seat all 31 fuses for whatever its worth.
I'm hoping this was just an anomaly that won't return any time soon. It's not a good feeling driving without turn signals....the car gets enough attention as it is, turning without signaling is just begging for one finger solutes and other hostile responses from other drivers...... it's also dangerous.
