2004 Ford Expedition A/C

Air Conditioning problem
2002 Ford Expedition V8 Four Wheel Drive Automatic

My A/C won't blow air out of the front vents. It works perfectly fine in the rear vents. I have checked all the fuses and there are not frayed wires. What could the problem possibly be?
Do you
have the same problem?

EATC MODULE SELF-TEST The self-test can be initiated at any time. Normal operation of the system stops when the self-test is activated. 1. To enter the self-test, press OFF and FLOOR buttons simultaneously then press the AUTOMATIC button within 2 seconds. Display will show a pulse tracer going around the center of the display window. The test may run as long as 30 seconds. Record all DTCs displayed. 2. If any DTCs appear during self -test, follow the diagnostic procedure given under ACTION for each DTC given. 3. If a condition exists but no DTCs appear during the self-test, see SYMPTOM TESTS. The EATC system is Inoperative, Intermittent or Improper Operation. 4. To exit self-test and retain all intermittent DTCs, push the blue (cooler temperature) button. The control will exit self-test, retain all intermittent DTCs and turn OFF (display blank). 5. To exit self-test and clear all DTCs, press the DEFROST button. The vacuum florescent display window will show 888 and all function symbols for one second. Then, the EATC control assembly will turn OFF (display blank) and all DTCs will be cleared. 6. Always exit 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. NOTE: The EATC module self-test will not detect concerns associated with data link messages like engine coolant temperature or vehicle speed signals. A scan tool must be used to retrieve these concerns. The EATC module self-test will detect concerns in the system control functions and will display hard DTCs in addition to intermittent diagnostic trouble codes for concerns that occur during system operation. The vehicle interior temperature should be between 40 -90 F (4 -32 C) when performing the self-test. If the temperatures are not within the specified ranges, false in- car temperature sensor DTCs will be displayed.
Post the results.
