Which AC panel unit does your vehicle use, the analog or digital?
Just have the old school analog. We have had about a month of temps pushing 100 and my AC has been running on 2 or 3 pretty much all the time. My average MPG has not budged off 34 since spring when it came up from the winter average of a horrid 32 MPG. In fact just last week I mentioned to the wife how impressed I was that my milage had not dropped with how much I have run the AC this summer.
