It's funny that I should see this two days after I tinted the windows in my S10. I did it because of the heat here on the Mississippi coast. Using the AC on my truck drags my FE down about 2 MPG. Since I have tinted the windows I am able to turn the AC off at times and still have the truck cabin cool enough to be comfortable. I "pulse and glide" it as mentioned by one of the previous posters. My next mod will be to identify which wire supplies power to the AC compressor and install a toggle switch on it. S10's do not have an on/off switch for the AC and I would like to be able to run the AC on "max cool" recirc mode with the compressor off recircing the cool air
