The floor vents in my Explorer do not work. If I turn them on, some heat comes out the defroster. I don't use the vent for heat because I don't want hot air blowing in my face. Lately, I've been using the defroster, but I don't like using that for heat all the time because it runs the compressor which uses more gas. My dad disconnected the compressor today. I hope I can get the floor vents working again so my feet are warm. The temperature's in the 20s today.
