[V8] two ways of heat

[Scott Simmons]

What are the odds that all of the seat heater elements have failed?  
None of them work, so I'm willing to bet that it's something they all 
have in common.  But from what I've read and can see on the wiring 
diagrams, they have separate relays.

What diagnostic procedures should I begin with?  Jumping the relays?  I 
had half my driver's side dash torn apart before the sun set, so I'm at 
a stopping point until tomorrow.  Does the lower column cover have to 
come off before I can get the lower dash pad off?  And if so, do I have 
to pull the steering wheel?

Second question, the heater valve apparently failed on a previous 
owner.  They just bypassed the heater core hoses.  I got a nice metal 
one from my FLAPS and are going to replace it tomorrow to give me some 
warmth.  The old valve split due to it being.. well.. plastic.  What 
kind of damage would this do to the car?  I assume that coolant gushed 
out of the old valve.  Where would it go and what kind of water damage 
would it have done?

Full of questions,
