[QUOTE="Gavin Allan, post: 1015116, member: 60736"] Fords never have as cold of A/Cs as many other makes because they use a fixed orifice before the evaporator in the refrigerant circuit instead of an always-adjusting thermostatic expansion valve like other makes use. With the orifice, especially at idle speeds and weaker flow across the condenser will result in diminished cooling. Add the very high dew points that exist in many areas of the country, and the poor Ford A/C struggles to remove any sensible heat, as most all of its cooling efforts are going to removing the latent heat from the intake air. Switching to recirculate can help quite a bit as the cabin air contains less humidity after a while. [/QUOTE]
