[V8] Cold-Feet Update: HVAC reports code-09 on channel 01

[robert_a_dupree at bankone.com]

If I read CJ Miller's site correctly, and IF it applies to the 1990 V8 
then it would appear I have an open coolant temp sensor circuit.
This having been the melted-harness car, I had to do tons of wiring work 
so possibly I missed hooking it up.

Questions:
1.  Can someone confirm that code-9 on channel-1 points to a bad coolant 
temp sensor circuit?

2.  Can someone articulate where on the car that sensor is, and where it 
goes to in the car so I can check continuity and the sender itself?

3.  Theorize on whether or not a bad coolant temp sensor would prevent the 
heater valve from opening?
