i have a 95 mustang 5.0 with a W4HO pcm & aode. the fans will not come on at operating temperature.ok,this is what i have done so far.applied 12v to the #14 wire and the low speed comes on.i then applied ground to the #17 of the ccrm and the high speed runs.i can turn the a/c on and the high speed works.i then replaced the ect sensor and checked the voltage at the return wire and it is showing like 0.46 volts going back to the computer at operating temp.according to what i have read at a little less than 1/2 volt the low should be on. the pcm for some reason is not giving 12 volts to #14 to turn the low speed on.has anyone ran into this before.i am thinking pcm. is there a way to check it first..i am also getting a code 564 (fan control circuit failure)...thanks in advance
