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).
Tell her to sit in the back!
Im not sure if there is a plug in there or not, but if you look at the very bottom of the glove box door you will see 2 screws, if you take them out and open the glove box, the whole thing will pop out. Maybe then you can see something, if not maybe go for a ride with the glove box out and have your wife feel down inside that cavity and try to pin point where the air is coming from.
Also if there is a vent, like some of the older cars have that lets in fresh air, it might be frozen or stuck open. Just some thoughts!
