Nissan Rogue Service Manual Cooling Fan Removal And Installation Remove harness retainers from fan shroud. remove cvt cooler hose retainers from fan shroud. remove reservoir tank hose from fan shroud. refer to co 13, "exploded view". remove fan shroud. refer to co 17, "exploded view". caution: be careful not to damage the radiator. installation. installation is in the reverse order of removal. 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.
Nissan Cooling Fan Wiring Nissan rogue service manual: wiring diagram. wiring diagram. ecu diagnosis information bcm reference value note: the signal tech ii tool (j 50190) can be used to. Pull the cover to the passenger side fuse box and locate the ac fan relay. should be in the driver side front position. now lift off the middle part of the fuse box so that you can get to the wiring underneath it. look for the wire coming out the bottom of the relay that is orange with a blue stripe. that's the one that goes to the ecu. 25 amp breaker or a 25 amp fuse is also suggested here by the fan manufacturer to protect. the controller system in case the fan were to short circuit. (5) blue wire not used, but can power up a second fan if needed. (6) green wire signal wire from a c power source, to the red and black wire in the single, light. Disconnect the drain hose from the heating and cooling unit assembly. disconnect the harness connectors from the heating and cooling unit assembly and steering member. remove the heating and cooling unit assembly and steering member from the vehicle as an assembly. caution: use care not to damage the seats when removing the steering member.

The fans are two speed fans. the fans should come on low, regardless of ac on off, when the coolant temp reaches 208f at any speed, or if the ac is on and below 212f coolant temp. if the vehicle speed is above 50mph then the fan won't come on low until 203f coolant temp. high speed will come on regardless of ac on off at 212f coolant temmp.
