Welcome to the forum!

I assume that your SHO has the Electronic Automatic Temperature Control (EATC) as I think that was standard equipment on the SHO. You can put the EATC in to diagnostic mode and see if the system recognizes a faulty blend door or something. You may try searching the forum for the procedure. If you don't find it, I'll try to remember to post it this evening.

Per the factory service manual for the 1998 Taurus with EATC:

d. To enter the self-test, press the OFF and FLOOR buttons simultaneously and then press the AUTOMATIC button within two seconds. The display will show a dashed line in the center of the display window. The test may run as long as 30 seconds. Record all DTCs displayed.

e. If any DTCs appear during the self-test, follow the diagnostics procedure given under ACTION for each DTC given.

f. If a condition exists but no DTCs appear during the self-test, refer to the Symptom Chart Condition: EATC System Inoperative, Intermittent or Improper Operation.

g. To exit self-test and retain all intermittent DTCs, push the blue (cooler) button. The control will exit self-test, retain all intermittent DTCs and then turn OFF (display blank).

h. The exit self-test and clear all DTCs, press F-Defrost button. The vacuum fluorescent display window will show 888 and all function symbols for one second. Then, the EATC system will turn OFF (display blank) and all DTCs will be cleared.

Always exit the self-test before powering the system down (system turned OFF). Intermittent DTCs will be deleted after 80 ignition switch ON cycles (after the intermittent condition occurs).
