The fan clutch on this vehicle is controlled by a module. This is a technical definition of how it works.
The cooling fan clutch is utilized to control cooling fan operation. This fan clutch is controlled by the ECM. The ECM monitors coolant temperature and intake manifold temperature to determine when to engage the cooling fan. There are also additional sensors monitored by the ECM for fan control (for example, air conditioner pressure and transmission temperature). The fan clutch is an electro-viscous fan clutch.
Since the fan is affected by several different items, the dealership needs to check the items listed above. The vehicle is under full manufacturer warranty. Thus, if you get no satisfaction from the dealer, contact the Nissan Zone Rep nearest to you. The phone numbers for customer service should be located in the owner's manual.
I attached a pic below of the item so you can see how it looks. If the dealer has replaced it three times in (at 10,000 miles), it's not the fan but one of the sensors, the ECM, or a wiring issue.
Let me know if I can help.
