This is a great post. I wish I could find detailed instructions and photos for other repairs like removing door panels, for example. But I can't believe you did all that work, practically dismantling the whole car, it seems, only to find the evaporator was most likely not the problem. Thanks for the note about the blower being able to be plugged with reverse polarity. I will keep that in mind if I ever have to replace it. This also sounds like a good lesson in why to replace the cabin filters on a regular basis.
