I own a Jeep Commander 5.7 V8 Limited and try not to drive with the air conditioner on, for fuel economy. But, I've discovered how you can get cold air out, without using the compressor and still get good fuel economy. I have the dual control with a vent dial and fan speed dial. If you turn the right dial to auto and turn the fan speed to where ever want it, with the temperatures dials all the way down, you will get cool air out, but the air conditioner light doesn't come on. I think the dehumidifier is taking the moisture out of the air and pumping out cold air, without using the compressor. Give it a try and see what results you get. dr burke.
Put in flush covers for fog lights. Collects dust and bugs. Put in a mini compressor to inflate tires. Fill tires with nitrogen for a smoother and quieter ride.
