How can I access the dtc codes through my Dual Zone a/c in my 2012 Expedition? Pushing the OFF and Floor buttons plus the AUTO button doesn't work since there is not actual "Floor" button to push. Front a/c comes and goes, rear a/c works perfect blowing cold.
Front a/c comes and goes, won't work at all if I put Recirc on or set temp below 70 deg, or manually set fan on high.

Used to be a high speed switch for the fan on older cars, but I'm at a loss with this 2012 Expedition

You could download FORSCAN on your laptop use it with ELM 327 bluetooth device. It can read most Ford dtcs.
