I have a 96 dodge intrepid. cooling fans run constantly. I overcharged the a/c last yr and thats when the fan issue started. I unplugged the a/c pressure transducer and the fans stop. the fans will come on when the engine gets hot in city traffic so that portion of the heat sensing system is working. the transducer has to be plugged in for the a/c to work. does it sound like the transducer is the problem here or could it be something else? i am not sure how the a/c systems gets it inputs to work. such as, compressor turns on, system pressure rises, computer senses this and turns on cooling fans. maybe just replace the transducer and see what happens.
