I just pulled my dash (I've done it twice before so I know the procedure)
and just thought I'd note that it took me exactly two hours with my wife's
help.  That's with no frozen fasteners, and includes splitting the heater
box (clips, not welds) in place to obviate the need for disconnecting the
hoses from the heat exchanger.  Immediately noticed one of the free-hanging
flaps lying on the bottom of the box, which correlates with the symptom of
very poor forced-air flow from the driver's-side cold-air vent (but good
flow from ram air).

The value of the blower resistor (someone asked recently) is 2.1 ohms, 60
watts, wirewound on a hollow ceramic core.  It is tapped at 0.7 ohms for
the medium fan speed.
