Hello and Welcome to Justanswer,

My name is XXXXX XXXXX I am here to try and assist your with your question.

Do you have electronic air (buttons) or manual air (knobs) ?
Customer: replied 4 years ago.
aelectronic
Expert:  Ron replied 4 years ago.
The blend door gets its power from the EATC controller. Before we go any further lets run the self test on the controller and see what codes are stored.

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 pulse tracer going around the center of the display window. The test may run as long as 30 seconds. Record all DTCs displayed.

Let me know what codes come up and we can go from there.
