Blazer1970 is exactly right. The AC pumps out dry air. If you have moisture in the cab and no AC all you're doing is recirculating that moisture.

My 1972 Malibu has "defog" and "deice" on the controls. Defog runs the windshield vents with no AC. Deice runs the compressor with the windshield vents. Deice clears the windows fast. Once they are clear you can use the defog setting. If I run deice with the rear window blower my windows are clear in seconds.

My truck doesn't have AC but I wish it did. The windows don't clear for crap in the summer when you are rolling down the road when it is raining and the humidity has been 95%+ all week.

On my wife's 1998 Exploder (Explorer) you can't turn the damn AC compressor off. When you start it in the garage you hear the compressor click on. If you sit there and idle you hear it cycle on and off a few times even with the heater control knob in the "OFF" position.

On my truck I made a screen for my cowl exactly like JimKshortstep4x4 did. Only I painted mine green to match the body color. No more bbbrrrrrrrrrrrrrrrrr when I turn the fan on in the fall.
