Reply to "Freeze-12"

Larry,

I was so jazzed about the cold air flowing out of the A/C I didn’t think about recording the pressure readings on their test equipment. They did say that the pressures looked good, but I realize that’s not very helpful.

Here are some links that might be helpful:

One of the many interesting things about the Pantera A/C system is how close the evaporator is to the A/C air exits. The evaporator is within a few inches of the outlets so I expect our temps might be lower than cars with longer ducting leading from the evaporator to the dash outlets. Some of the older GM cars have their evaporator in the engine compartment.

The strangest thing I’ve seen is on 71 cars with the outside air connection between the cowl and the AC box. The connection is downstream from the AC fans, so if you open the air control it blows condition air out of the car into the cowl opening. This might work differently when the car is underway.
