It needs replaced because these fan motors are a sealed unit. They are lubed when new and are supposed to last at least 10 years or more.

The primary radiator fan does not come on.


Check Maxi fuse #3 60 amp in the under hood electrical center #1 .This is power for the #1 cooling fan . Also check the #1 fan control relay in the same under hood electrical center .
These vehicles use 2 360 mm (14.2 in) cooling fans to aid air flow through the radiator. Electric motors drive the cooling fans. These motors are attached to the radiator. Motor size varies with each engine option.
A coolant temperature switch activates the fan motors. This switch regulates voltage to the cooling fan relay. This switch operates the fan whenever the engine coolant temperature exceeds 110°C (230°F). For location and diagnosis, refer to Electrical Diagnosis. A transducer can also activate the circuit, depending on the A/C compressor head pressure going to the condenser.
The engine cooling fan relays provide the high current required for the cooling fan motors using a low current signal coming from the Powertrain Control Module (PCM). This signal is a function of various inputs.
Refer to Electrical Diagnosis for further information and diagnosis of the cooling fan relay.

Where is the fuse for motor fan in uplander 2006?


there is 2 fuses that you have to check
one will be in the big fuse assembly in the engine bay, the other probably in the fuse assembly in the cab
If they prove ok then it is possible that the coolant temperature SENSOR is faulty and needs replacing
don't confuse it with the temperature sender which operates the temp gauge.

Mini Cooper 2002 overheated, fan fuse keeps blowing


The most common cause for the cooling fan fuse to blow is a bad cooling fan motor. The failng motor will draw an excessive amount of current which actually heats up the fuse and melts it. Now if your fuse is blowing the instant the cooling fan(s) turn on, then that could be a "dead short". either inside the cooling fan motor or in the wiring going to it. Follow and inspect the wiring leading to the cooling fan motor. Check for any broken, cracked or burnt wires. If you don't see any of that, then you'll probably need a new motor. If you think you can tackle the job, most auto parts stores sell generic replacement cooling fan motors much less than you would pay at the dealership.
WARNING! - some cooling fan motors are easy to get to, and others are very difficult. Study yours carefully and then decide if you want to tackle the job before you start tearing it apart.

Cooling fan not turning on


Check power to and operation of the cooling fan relay. (location shown in pic) If good, then test for power to cooling fan motor. If present & motor has good ground then it's a bad fan motor. Pic is for vehicle with 2.2L engine.
