Thanks Jack.
The shut-off valves are going back in.

    The Winged Warrior had a substantial amount of heat entering with the heater turned off. Actually, on or off, it's the same amount of heat. Is this typically due to a bad heater valve?


  No- a bad design. Many or most stock Pantera heater shutoff valves CANNOT turn off the hot water entirely, AND open the valve fully when you want heat. The cable linkage under the dash has levers that are the wrong length. You can adjust the cables for full open, or full closed, but not both. 
  Plus, when the valve leaks hot water thru the heater, the A/C must then overcome the heat from that hot water before the occupants get any coldness. THere are various fixes but the quick, simple fix is two manual shut off valves in the lines. Cheers- J Deryke
