I've noticed that when I have the vent on in my car, the compressor is engaging. Same thing when I have my defroster on and my "mix" on as well. I would assume that the compressor would come on only when I hit the Max or Normal Air switch. Would some of you guys do me a favor and turn your cars on and see if the compressor engages while on defrost , vent, and mix please? Thanks
