OK,dug into mine a bit and removed the heater duct below the dash and found a ink pen in there and thought that was easy, removed it and still the same. So I had a buddy moving the selector switch and on the drivers side under the dash you'll notice a white plastic selector plate with 2 rods running to it that wasn't moving in to all its positions,I pushed it to the middle position and waaaalaaa it went to defrost, couldn't get it to move correctly via the cable, but hey I can do it by hand for a bit, or leave it there and where boots.Hope this helps Griz.Goodluck METALMOVER
