2010 Ford Fusion


Topic starter

My 2010 Fusion is driving me nuts.  All the blend door actuators are good.  The climate control module is good.  The evap temperature sensor was recently replaced.  I have cool air coming out of the defroster vents, and I cannot select other vents for the air to blow through, and cannot switch from cool to hot air.  If I pull the fuse and wait a few minutes, I get hot air blowing out of the dash vents, but still cannot change what vents the air comes through.  When I turn the key to the on position with the heat off, I can hear the blend door actuator near the gas pedal cycle back and forth twice, then stop.  Then either later that day or the next, I have cool air coming only through the defroster vents again.  I cannot figure out how to fix this.  Someone please give me some help or ideas.

Well unfortunately those things are all computer run and the only way you can work on is with a dealer level scan tool that does bi-directional testing and then shows how the data changes as you test different modules. That's just how complex they make that crap these days I can't stand it either

Thanks Scotty. I figured I would probably have to do that but was trying to avoid a huge repair bill. I miss the days back in the 80s when cars were so simple to diagnose and repair.
