Hi Mary ANN , need some clarification ,the fuse's for all these thing's you have listed , the tail lights, hazard, headlights, blinkers, cruise, brake lights, coolant fans are good ? If good what makes you think you have a short ? Explain ! Are these thing's not working ? That wouldn't mean you have a short . You could have a bad ignition switch !
check cruise control fuse and check the brake lights see if brake light working because the brake light switch will deactivate cruise control when brakes is applied.if brake lights dont work either fuse blowed or switch bad.if all is good have vechicle code scan because cruise control control by PCM and vechicle speed sensor and thottle actuator control motor.
cruise control best let garage check out,here are few things to check,check fuse and check to see if brake lights dont work.check brake light fuse if fuse okay brake light switch could faulty or bad connection then brake light will reset cruise control you apply brakes.if all is good problem could be speed sensor or accelerator pedal to ecm.you need diagnostic euipment to troubleshoot.
There is actuly 2 differant fuse #12 the brake fuse #12 10 amp and fuse #1 the stop and haz 20 amp .But neighter are likely the problem . There is another brake switch for the cruise control called the TCC brake and cruise control relese switch that tells the transmission when the brake is applyed and shut of the cruise control . This is more likely the problem its up under the dask near the steering colluom follow the wires from the main brake switch on the pedel if you have a standard then it will run through the clutch switch as well .Fuse #12 also controls the muilty function switch but fuse #1 is the brake input switch . So if the lights and blinkers work i would look at the TCC brake switch first thank you
in stop pedal youll see the stop light switch,remove the botton cover and you will find it,check it whith a test light,it should be normaly open,so one side power and the other ground,depresed power in both side ok,GL
