So I get in the PacHy this morning for a short trip. To maximize fuel economy I turn the climate control off even though it’s only 20 degrees outside. The defrosters are off, no seat heaters or heated steering wheel. I start driving but I notice that by fuel economy just isn’t as good as it normally is in all electric mode. So I switch over to the screen that shows where the current is flowing and, lo and behold, it says that climate control is drawing 5 kW! I re-check all of the controls and verify that I’ve got nothing turned on. As I drive for some 5-6 miles the current draw eventually lessens to 1 kW. What is causing this?
