Welcome to the forum!

What year is your Explorer and does it have the electronic or manual HVAC controls?

By damper door I trust you mean the blend door. The blend door is electronic and controlled by the temperature set point potentiometer. The blend door actuator is located behind the RH side of the instrument panel, at the top of the A/C plenum.

You may want to verify that the 7.5-ampere fuse in location 10 of the instrument panel fuse box is good as that is the fuse that powers the blend door actuator.
