So I dug into it tonight:
1. The GOOD - Verify if cable is seized from Heater Control Servo to the Water Valve in engine compartment - by disconnecting cable on both ends and trying to move it. RESULT - Cable is NOT seized, moves fine.
2. While cable is disconnected, see if Heater Control Servo lever moves with the turning of the Temp Knob... RESULT - Didn't do this, but it wouldn't have moved since cable was good. And something else is bad.
3. The BAD - Took apart the Dash Climate Control Module to spray with Electrical cleaner. DONE... Then did something stupid. I rem'd the flat cable connecting the 2 electrical boards in the Module, could not get it back connected, and messed up the ribbon contacts. So ordered a used module from EBay for $100... Mad at myself about this... As I didn't need to disconnect. But then, I did have problems with this very module a few months ago. It was flaky.
4. The Good - Removed Heater Control Servo Motor (where cable from engine compartment connects). This was easy to get out (3 mounting screws and a cable clamp screw), but will be a bit tougher to get back together. The Servo Motor lever is stuck solid when trying to manually move (but this is correct - don't force it), but I did see a video on how to connect the motor to a battery and test. (

Results to this point.
1. HVAC Blower Control Cable (87286-35040) is good
2. Heater Control Servo Motor (87106-04030) is good.
3. Climate Control Assembly Heater A/C Control (55912-35030) was probably bad (if not, I made it bad).
Now to wait a week plus for my parts to arrive... But I can now put it all back together... as the Climate Control Assy is an easy replace...
