Nissan Cooling Fan Wiring The fsm also describes testing the various harnesses and connections between the relays, fan motors, and the cpu. the cpu is supplying the 12v to the motor windings and the relay operation supplies the ground. the relays supply ground to various windings of the motors for the different speeds. the fsm also cautions not to overheat the engine. Each fan has four wires. if it was two and two, i could get that quickly, but each fan has a four prong connected and two wires running to each side of it. yes each fan has four wires, the colors i specd and the other 2 are grounds.fan 1, wht red, wht blu, blk, all these are on one side of the fan.on the other side is awht blk.
Diagram 1983 Nissan Sentra Cooling Fan Wiring Diagram Mydiagram The cooling fan operates at each speed when the current flows in the cooling fan motor as per the following. the cooling fan operates at low (low) speed when cooling fan motors 1 and 2 are circuited in series under the middle speed condition. refer to ec 1099, "system diagram". component function check. 1.check cooling fan function. 1. 1. first find the cooling fan schematics. 2. locate the ecu pinout for the cooling fan relay hi control. in this case, i am using a '95 ecu pinout that shows pin 13 for the cooling fan relay hi control. note: if you prefer manual control for only low fan speed operations then use ecu pin 14 instead for cooling fan relay lo control. 3. 41 posts · joined 2020. #2 · nov 28, 2020. one fan is for air cooling the ac condenser while the other fan is for maintaining engine coolant temperature. both fan will must likely maintain engine coolant temperature since the engine will have the likeliness to idle 50rpm above normal engine rpm. the compressor clutch has a great effect on. A typical nissan 350z radiator fan wiring diagram will show the wiring, connectors, and terminal locations, as well as explain the current flow through the system. it’s great to know the inner workings of your vehicle, especially when it comes to things that require precision wiring. properly understanding the diagram can help you to.
