When I have the heater on I usually have the thermostat set to 77-80. I have the vents set to blow on the floor and on the windows (1st and 3rd buttons on top row of controls, with "auto" and "recirculate" off), because I don't like hot air blowing in my face. The heat will blow hot on the windows and the floor for a while but eventually, for some reason, switches to blowing cold air on the windows but stays hot on the floor. If I bump the temp up or up and back down, it does the same thing. Blows hot through both for a while, but then switches to cold on windows, and remains hot on the floor. When it changes the temp of the windows vents, the air blowing on the windows is cool enough that it feels like a window is open. Is this normal??
