Been driving a 2011 Sienna with 85,000 miles since March this year. While driving with windows all closed no problems. Lower either front window 2" - 3" the dome lights turn on and the alarm lights show on the dash. Raise the windows and the lights and alarm turn off. I think this might be an air pressure problem. The Sienna is so tight, lowering the window while moving creates enough of an increase in the interior air pressure to cause the rear hatch to open just enough to cause the lights to and alarm to come on. Is this possible?
