Ford Focus Cooling Fan Wiring Diagram Wiring Digital And Schematic The ford focus cooling fan wiring diagram is an essential part of keeping your focus running optimally. it connects the cooling fan to the vehicle's electrical system and allows it to run properly. without a reliable wiring diagram, your fan could overheat or even stop working altogether. this can lead to unwanted repairs or even engine damage. If the fans don't work with the ac on, then you need to diagnose the fans with a resistance test to see if the fan motors are working. if the fans work with the ac on, then you need to bypass the resistor on the low speed circuit by simply tying the 2 wires going into the resistor pack together. this will effectively bypass the resistor and.
Ford Focus Cooling Fan Wiring Diagram Wiring Digital And Schematic The ford focus cooling system diagram depicts the flow of coolant throughout the engine, radiator, and other components. it consists of several key parts, such as the radiator, water pump, thermostat, and hoses. each component has a specific role in maintaining the engine’s temperature within the optimal range. My 2012 radiator cooling fan comes on sometimes when opening closing the doors, comes on sometimes (while driving) in the 90 94c temperature range, and engine overheats (111c) occasionally. installed new thermostat about a year ago, and hoses get hot at the appropriate times. coolant flush about 1 year ago. throws p0219, p0480 and p0217 codes. Looking at the diagram: the relays are controlled by switched grounds at the pcm, behind the right side of dash near base of a pillar. if you were to add a manual switch to ground out those control wires, you should be able to manually switch on the fans. high speed cooling fan relay: blk wht, # 31s pa17, terminal # 17 @ pcm.
