I'll bet you guys nailed it..
For some reason, I didn't think about the two fans!!
I know the radiator fan never comes on unless the engine gets up to the 200 deg range.
But, I'm unsure if the AC needs a fan running when the car is going 55 MPH..?.
I guess they would just turn it on anyways, in case you were sitting at a long traffic light..
I guess that those fans really do work, even if you are at highway speeds.
My crazy theory may have some merit.. IIRC, there was a guy around here installing insulation on his AC pipes under the hood.
He figured the pipes that were frosting up, were just wasting
'Cold' that he wanted inside the car, not under the hood..
Now that I think about it, it's nice that my AC still works okay with
80% of my grill intake blocked off.
