Ok, I posted yesterday with the A/C problem in 2002 F150 SuperCrew. (A/C defaulting to the Defrost vents... etc.) Had it in to another shop that did a vacuum test with the smoke machine and found no leaks... other than that did virtually nothing to the truck except to tell me that it is possible that this year model might have an electric motor that controls the "Mode Door" (Not the "BLEND" door, as everyone agrees that is electric...) rather than the vacuum control that folks have suggested it might have. The guy at the shop said this was likely as it has the "semi-automatic A/C" versus the manual control that the earlier year models had/have. Can anyone shed any light on this, either verifying that this MIGHT or MIGHT NOT be the case, or just debunk this statement altogether? Any help is appreciated.
