I would say that this problem is caused be a vaccum leak. Ford was known for using vaccum in their heat/ac systems....and you loose vaccum as you press the accellerator.

I had this issue with a Grand Marquis....and was a pain to find the leak.

You really need to look over all the vaccum lines that run under the dash.

Cold air like, really cold or just cool. Sounds like your hot/cold blend door motor has perhaps failed with the blend door in the semi hot position. Blend door motor failure is very common on the Ford truck HVAC systems. Is is located behind the glovebox on top of the HVAC housing assembly.
