My wife unplugged our 2014 Prius (23,000 miles), opened the passenger door, sat down. All the doors locked and all the aux items went on - dashboard lights, display, A/C fan on high. She tried to unlock her door using the power lock button, but it was not responsive. She reached over to manually unlock the driver's side door, and I got in and sat in the driver's seat and pushed the power button, which shut off the car. The power door locks then worked, and the car started normally. Anyone know what might have caused that? We were freaked out....
Perhaps, you pressed (by accidentally?) the AC button on your FOB remote, after your wife got in. Read the owner's manual to see how it works.
