trucks hot

[ford1386]

i have 94 ranger and in 70 degree weather i cant drive down the road with just the window down i have to turn the air on because even though the fan is off and none of the vents are open (in off position) i still feel heat coming in through the dash vents. one of my co-workers has a zr2 s10 and says he has the same problem. could it be that a flapper is not closing the whole way or is it heat coming from the motor somehow?? Or is that just how it is but i dont notice it in my 2001 super duty at all.

It's the blend door.

Well documented throughout the Ford model lines.

I googled "Ford blend door" for you,
