I have noticed that there is cold air blowing out the vents when it is warmer outside. The frist time was about a month or so ago and it got 87 degs out. I was driving on the interstate with a light jacket on and noticed that I wasn't getting hot. Felt the vent and there was really cold air blowing out of it. I had the fan speed on low and turned it to high and the air got warm fast. I then turned the ac on and then it got cold. I noticed that my MPG gauge really dropped so I turned it off again. The air got warm so I turned the fan speed to low and the air was warm coming out the vent. About 10 miles later I checked the vents and very cold air again. This leads me to believe that my AC clutch is draging. I have noticed on the foggy mornings that the water is condensing on the outside of the windshield also when the vent is on. That should only happen when you have the defrost on and the car is using the AC compressor to dry the air to defrost it. Wondering if anyone has noticed that also. I have averaged 40 MPG so far but wondering what it would be with out the clutch dragging and killing my mileage.
I think my air conditioner clutch is dragging when it is off
