Gee, you would think that Ford would at least have their manufaturer void that vent on those dashboards that are going to the ST's. Oh well, I guess it was cheaper to just let them sit there like an extra useless finger on your hand! BTW< does anyone know if those same "useless :wacko:
The same dash was used in the 1995 to 2001 Explorer and still used in the Rangers. It is much more cost effective to use the same kind of dash for all vehicles. It is where the ETC on a high end Explorer would get its internal temp readings.
I swear that my 04 Audiophile head unit has a fan in it. After extensive use and when it's hot, I can clearly hear something whining in there. It stays on even after turning the headunit off. So maybe that little kidney-shaped vent has a use after all? Or not, as Robert Poole just explained what it was for.
Since the '07 can come with automatic climate control, a similar vent isn't useless on those models. Of course, on models without automatic air conditioning, the vent is useless.
