Anyone know how to turn off the A/C when it comes on automatically with the defrost? My Honda Accord comes on with the defrost but can be turned off by pushing the A/C button. The Aerio SX 2004 A/C switch doesn't even light up when the defrost is on.

 

I dont think that I have seen/worked on a car made in the last 20 years which did not have the built in function of the AC compressor kicking in with the defroster. all of my cars do it, even my old truck.
