RE: Auto Temperature System- I don't get any heat???

Well, the climate control system in the 5kCS usually runs hot water through
the heater core ... even when the air conditioning is running at anything
less than max cool!  I would suppose that you have one of 3 problems ...

1) someone disconnected the heater core because of a leak
2) someone plumbed the vacuum to the heater valve incorrectly so that it is
closed all the time
3) the Bowden cable for the "blend doors" is disconnected, or the motor that
drives the cable on the A/C programmer (behind the glove box) is busted.  

While my prime suspect would be #3, the other two are easily checked by
following the heater plumbing off the back of the engine ...
