Update-OK, went through the entire system. Vacumn hoses brittle and leaking, thus the blower controls won't work correctly. (Fixed) Removed the thermostat, what a mess, it appears someone used something to stop a leak. I found what looked like hardened foam in the thermostat housing, started to clean it out and found a hole about the size of a pick in the housing.(Fixed) Replaced housing, new 180 thermostat & gasket. Before I put it all back together, complete flush, then back flush, pulled the heater control valve in the heater hoses, installed new heater hoses. Flushed heater core. 50/50 Antifreeze. (Fixed) Looks better, runs @ 180* on the money, verified with (DRBII Modis Scanner) no gauges, and the controls work the way they were supposed to run. I still can not find the heater valve control cable, and the black & white vacumn lines are repaired, black to the vacumn resv. The white I just installed a check valve.
