Bit of a project today on ranger. I did the original service on this truck before I bought it and I didn't notice the mode door making noise until a few days after I had bought it, everything worked fine but when I shut the truck off I could hear a buzzing noise. Traced it down to the mode door binding plus it was setting a B1086:07 code which is for Air Distribution Damper Motor component fault, which is a bit misleading as the motor works fine but because something was binding it could not move freely.
So while I still had my 60 day warranty I pulled the dash and replaced the whole upper air box assembly. Wasn't a horrible job took right at 4 hours, I was able to get the air box out and back in without evacuating the AC or removing the heater core which saved a bunch of time. Everything back together working great and I can tell a difference when I select full floor mode.
