Another 03 Nav. A/C question

Hi everyone,

I searched on the FAQ's and around the site here and couldnt find a similar situation.

My nav. when I put the air cond on auto and lower the temp so the air comes on, it blows out the vents on the front of the dash like it should and is cold. Then after about 30 seconds give or take, I hear a door deep inside the dash shut, or open, then the cold air only comes out the dash vents that are the defrosters for the windshield.

Then I can make it go back to the front vents again by pushing the button on the heater control to make the cold air come out the front vents again, but then it does the same thing again.

Anyone have any idea whats going to need to be replaced/repaired?

You have Ford's infamous blend door problem, there are numerous threads in the Expedition/Navigator forum dealing with this, There is one with pics or a video for a repair that does not require removing the dash.
