if you let off acceleration it will blow cold. cant tell if a/c clutch is cycling correctly. Recent misfire in cylinder 4 and a/c started doing this. recently had intake replaced. ran great until positive cable post connector cracked and I replaced it.
a/c blows cold while at an idle. Blows warm when a small load is on engine. on 1999 Ford Crown Victoria

Is it changing temperature or changing 'where' the air is coming out? Switching to say defrost instead of coming out of the dash vents?? Let off gas.... Starts blowing out dash again....
