OK, going to throw a monkey wrench into all this. For me, it may be that the AC actually uses 15% of the fuel on the highway. It got cool here for a while and with the AC off, in some short distance samples, the MPG numbers seem to be closer to what I was getting before the recall. I expect to be taking a longer trip in about a month and that will confirm if this is the case. And if is the case, why is the AC using so much power? I believe it's suppose to be a variable output compressor. Maybe that logic has been messed up. I have noticed that after on the highway a while the air is extremely cold from the vents. Would save energy if the compressor was turned down a bit and the fan turned up a bit.
