Hi.  In the last week the A/C on my 2012 Ford Edge Limited has been acting strange.  I have the Sync system and while driving down the road, my A/C with increase the fan speed with no one touching the buttons!  And its not in AUTO mode to regulate the temp.  So since its cooling down a bit, the A/C was off and again out of the blue with no one touching any buttons, the A/C popped on and increased the fan speed.  I swear its possessed.  Can there be a stuck mechanism behind the panel?  Has anyone else had this weird problem and how was it fixed?  Thanks for any info!
