Anytime I put the vents to the floor the AC comes on, I can have the AC button turned on or off but anytime the vents are on the floor the compressor comes on and it blows cold air. I have the temp set to 60 and I'd expect that if I was pushing the floor and defrost button but I cant turn the floor vents on without the AC coming on, anyone else having this issue or any suggestions as to what I can do?
