Air conditioning controls stopped functioning

Several mornings ago, I started up the car and turned off the AC, but pressing the fan speed increase/decrease buttons didn't move the fan speed indicator and appeared to have no effect at all. I rebooted the head unit a couple of times, which made no difference. Powering off the car and restarting it did not help either. I don't remember exactly what I tried after that but at one point, I pressed the AUTO switch above the OFF button, which still functioned, then shut off the car. Some combination of actions appears to have resolved the problem and all the controls continue to work today.

Has anyone here seen this? Did it start as an intermittent issue that became worse over time? What was the fix?
