My 05 SCrew is not only my work truck, but our "family" vehicle and lately my wife is constantly complaining about cold air blowing in around her feet. If she stuffs her toes up under the heater duct, it's ok, but out by the kick panel and door, there's a breeze. Any ideas on where to stuff some insulation (no, not in her mouth, thank you!)? Can I just shove some insulation up under the glove box area? Anything I'm going to stop up in there I shouldn't...... I don't know if a plug in the firewall has been knocked out or what but it's very uncomfortable and becoming more and more of an issue as it's so stinking cold (for KY, anyway).

Thanks!
