My 97 f 250 blows fuse # 6 which is a/c and fuel selector switch. I unpluged a/c comp. but still blows fuse. Were do i start looking for problem the fuelswitch/valve/wiring ect.

 

check to see if the ac wire is grounding out on something metal. follow your wiers to make sure your hot wire doesn't short out. if you unplugged the ac unit, that means your prblem may be in the switch itself. email me back james
