The panel at the driver's knees is held in place by a couple screws you get
to by taking off the dash endcap, as well as a screw under the steering
column and a screw down near the brake pedal.  You do not need to remove
the lower steering column switch cover.  Isn't there also a fuse associated
with the seat heater relays?

Do you know for a fact the plastic heater valve split?  It's also a common
practice to bypass the heater core when it starts leaking.
