You are right on the money. I still have one and it runs great, but that dang blend door is a problem

Yep, My 2011 F150 is a sweetheart and I love her like a rock. Air cond will chill ya on a hot Arizona day. But the heat is non existent. Iv read the problem is the blend door. Searched on the fix and it seems you have to almost pull the dashboard out to get at it.
I'm hesitant to do that, so I wear a coat on any morning drive.
