Do you mean the blower does not work other than in the position and condition described?

Perform the following to see if it works.

IN-VEHICLE CALIBRATION
NOTE: Whenever heater control panel, heater unit, doors or door actuators are replaced, actuator calibration/diagnostics test must be
performed.

1. Mode and blend door calibration compensates for mechanical differences in actuators, heater unit and its linkages. In-vehicle calibration is entered using switches and buttons on Heat Vent Air Conditioner (HVAC) front panel. If rear wiper and intermittent LEDs flash simultaneously when ignition is turned on, actuators have not been calibrated or a previous calibration failure occurred. Diagnostics will always occur during calibration.

2. To enter calibration/diagnostics test, set parking brake. Start and warm engine to normal operating temperature. With engine idling, turn blower switch to high. Turn mode switch to panel (air comes from instrument panel outlets). Move temperature lever to full cold. Press
and hold rear wash and wiper buttons for 5 seconds (until all LEDs illuminate). Rear wiper and intermittent button LEDs will flash alternately during calibration test.

3. After approximately 60 seconds, if only wiper button LED is flashing, calibration is successful and system is okay. If wiper and intermittent LEDs are flashing, see DIAGNOSTICS under TROUBLESHOOTING for diagnostic procedures.

4. To exit calibration/diagnostics test at any time, press rear wiper button or cycle ignition off and then on. Test will automatically terminate 15 minutes after calibration/diagnostics is entered.
