This is a question for any of you that have had your A/C evaporator assembly apart or have removed it. I replaced the blower motor on the evaporator fan last week. On the bottom(inlet) side of the evap. coils there is the duct that comes from the area under the passenger floorboard, then there was another hole in the bottom of the evaporator casing. This hole came from the centerline of the car. Am I just stupid, because I couldn't figure out where this duct is coming from? I thought that the A/C system on a 1980 911 was purely a recirc system. I should've taken a pic, but was in a hurry to get everything buttoned up.
