Fan in nissan pixo 2009 making noises on number 1 any reason why please


The fan bushing are wearing out,, at low speed it just wobbles around, when you speed up, it "self-centers" and stops making noise... won't be long before it starts making noise on all speeds.. just prepare for replacement.

I have a GMC 2003 Envoy, each time i drive it sounds like im speeding but im going really slow , i need to change the oil could this affect that and what do i do about the sound


Difficult to know what sounds like speeding: engine, road noise, what ?

If the oil change were to help, you have bad, bad engine problems. I suspect you may have a wheel bearing that may have failed. This makes a lot of road noise, alters with vehicle speed and NOT engine speed (drop to idle, noise the same).
There is a possibility of transmission slipping. this lets your engine speed up, but not actually move the car.

There is a third common issue and that is FAN. When your fan clutch fails, is locks up a normally free spinning (somewhat) fan, as if the vehicle needed max cooling... This noise follows engine speed, the vehicle seems to go just fine, but huge noise.... This sometimes is called Jeep fan noise, as many of those used to have direct drive fans.... If this is your case, the fan clutch gets replaced, not huge $, but more than it should be.

In my hp 61020 mt destop am facing the fan speed and noise is too high....any solution to this....


It may be just that the fan needs to be replaced.

More likely is that the computer cpu is overheating and the motherboard is ramping up the cpu fan speed to try to cool it, hence the high fan speed and consequent noise. This usually happens when the heat sink is clogged with a lot of dust. It could just be that the fan heat sink came loose.

It may be that it's just a noisy fan, in which case replace it with one that doesn't make as much noise.

My Hawkins 44" fan makes a humming noise when the fan is going. The faster the speed the louder the noise. With light on only , no noise. My assumption is it is electrical. Any advice would be welcomed....


Unless it is really loud, the noise you describe is quite normal. Often, at higher speeds the whooshing of the blades will mask some of the motor sounds. we have found the Hunter fans to run the quietest.

Heater blower only works on hi speed Rav4 (2004)


I don't know much about Toyota's but, usually when the fan only works on high it's because the blower motor resistor is bad. When you have the fan on high it puts full battery voltage to the motor. When you have the switch set in any other position, the battery voltage is routed through the resistor. When that happens the voltage to motor is redeuced through a series of resistors giving you the different speeds. The resistor is usually in the duct work fairly close to the blower motor. Good Luck!

Heater fan motor


The fan motor can be checked by using jumper wires. remove the wiring connector from the fan.Run the positive wire from the battery to the positive on the fan and the ground to ground. It should turn smoothly and at normal speed at 12 volts.If it is slow and noisy, the bearings making the noise. This indicates the motor is bad.
