Thanks for the detailed instructions Beatnik!! They were to the T. And as Beatnik suggests, make sure you use a universal joint especially to get to the back screw that holds the card in place. I didn't have one and it took about 1/2 an hour to one hour just to get that one screw out. Needless to say that back screw isn't in there right now.
Also you really don't need to remove the blower motor just look past it and you'll see a blue connector plugged in. That's the resistor card.
Also instead of the 5.5 mm use a 7/32 socket it fits perfectly. I didn't have a 5.5mm socket and experimented and the 7/32 socket fits like a glove.
