I believe that this was discussed recently, but I've searched and can't find it.
I have a 2009 Ranger, but I'm sure my issue would apply to virtually any Ford. What's happening is sometimes when I start my truck and turn the HVAC on to defrost, I get a handful of leaves falling out onto my passenger side floor mat. What really intrigues me is that these leaves are still intact.
I thought that the outside air was drawn in through the cowl, which on my Ranger has holes less than 1/4" in diameter; the underside of the truck is at least a foot off the ground, so they wouldn't get drawn in that way, and besides, how does a leaf get past the evaporator or heating coils? I don't park under trees anywhere - I'm baffled by this.
Hopefully one of the fine members here will be able to shed some light for me.
