Not sure if I should post this thread in the engine/ drivetrain forum or electrical. 1999 F250 Super Duty with Triton V10. Fuse #3 in the cab which is for the cigarette lighter and OBDII blows the fuse as soon as it is inserted . I think a sensor has a short causing this, anyone have any ideas on how to find the cause? Truck hit a deer about two months ago and has some front end damage, but airbags did not deploy. Two sensors I have noticed damage: 1> Passenger Side behind front fender and headlight (Air Bag Sensor?) which is where the body damage occured, and 2> on the front of the valve cover on drivers side (both wires broken off).
