Update - the driver side blend door is for the hot/cold door. I removed it and was able to manually move the door back and forth, no blockage.
After talking to the service department at ford they said that the 2008 edge is Plummer for dual climate control even of you didn't get the model that has the feature.
What this means is that there are 3 blend doors. The 2 already mentioned and the one up by the evaporator or under the dashboard.
This one is used for the dual climate control; again, even if you dont have the feature.
So what seems to have happened is that this valve or door or whatever you want to call it is stuck/moved, into the cold position for the driver side.
This is why when I turn on the A/C and high heat, the driver side gets cold and the passenger side is hot.
Now, the fix.......any ideas? I assume I have to remove the dash board but I am really hoping I don't have to.
Help?
Thanks
