first up, whats goin on to whoever reads this post.. my name is tbone. i have a unique problem with my car that i need some sound advice as to how to troubleshoot and remedy the problem properly. i have a 91 infiniti m30 with about 120,000 on the dash that decided about two weeks ago it was gonna blow air whether i told it to or not because when i went to start my car a strange thing happened.. my ac/heating fans began to blow cold air through the floor vents inside my car... this would be just fine except this was without me turning it on and for some reason it wont shut off no matter what i try....it comes on at almost full blast as soon as i start my car and will not slow down nor stop blowin cold air regardless to what buttons i press on the dashboard and it wont shut off until i cut the car off!!! i have held back from tinkering around for fear of damaging anything and am looking for advice as to where i might start my search in trying to track down why these fans come on uncontrollably the way they do. if you have any theories at all please let me know i could use the input ............................................................thanks
