Last night I drove a short distance. I started the car and let it run with the heat on while I went back in the house. When I came back all the interior windows were fogged up. I turned on the defrost and it did all clear up but as I drove the display started cycling through all its screens. The map stayed in place, just the inset of climate and radio. On the return trip it was ok but i noticed that even though the car was in EV mode the engine was running and it did not use any of the battery power. Scanned for codes and it came up with PO1443 under AC. Stuck purge valve. 2017 Prius prime premier 118k.
