I have a 2013 Edge that has the My Ford Touch system. The other night it was around 72 degrees outside with high humidity, so the water vapor was condensing on the windshield. Instead of constantly running the wipers, I will usually turn the defroster on with heat to keep the condensation off. I didn't get anything above the ambient temperature out of the vents.
I am wondering if there is something in the software for this touch screen that limits the heater from coming on if the outside temperature is too warm, or if it may be something else entirely like a bad thermostat. I didn't have any problem with the heat last winter.
Thanks for any help on this.
