Heater problem
1998 Lincoln Mark VIII V8 Two Wheel Drive Automatic 113124 miles

Car has no heat. Coolent levels are ok. Car operating temperature is perfect, checked all lower and uper hoses and both sides of heater core is, water is flowing at proper temperature. Checked blend door behing glove box it seems to work ok. I have pulled the grey plastic lever down 1/2 inch on the blend door to get temporary heat that did not work. Ac is fine and all vents flow properly.

Ensure coolant temperature is at least 120 F (49 C) before entering self-diagnostics.
Turn ignition to run position (engine off).
Simultaneously depress OFF and FLOOR buttons on EATC module, then press AUTOMATIC button within 2 seconds.
Display will show a pulse tracer going around the center of the display window for up to 30 seconds while test is running.
