My bmw750li has a loud fan noise that randomly comes on. It seems like it happens when I get low on gas. It sounds like a blower going up and down. Could it be an oil filter? Fuses?please help


When the engine temp reaches a certain temperature, the aux fan automatically shifts into high speed. It is a bit loud. Does the fan noise come one while idling for a long time?

My fan speed is stuck on hi no matter were I set it. Also it stays on when you turn it off and it stays on for about 10 seconds after the car is shut off.


I would replace that switch first thing since there is nothing that can make it stay "on" other than itself.

94 Buick Roadmaster AC fan blowing hot and won't shut off


If you have climate control it could be the main processor. Something could be shorting the blower relay to keep it on. You would also need to check and see if the system is still full of freon.

Turned on interior fan speed and heard a loud noise, then nothing. Air speed now doesn't work.


More than likely the squirrel cage fan attached to the blower motor has broken or come apart causing it to bind up in the housing making the vehicle blow a fuse. Check the fuse block for the blown fuse then try the switch for the fan speed again if no noise, you may want to inspect the fan for damage.

The heater when I turn it on high blow it makes a noise like I can here a fan running and when I turn it down you can here it shut down. Note; the blower only works on high.


LOWER SPEEDS FOR HEATER / AC ARE CONTROLLED BY A RESISTOR. IT IS NORMALLY LOCATED UNDER THE RIGHT SIDE OF THE DASH, NEAR THE BLOWER MOTOR. APPROX. 2 1/2 INCHES LONG, HELD IN WITH 2 HEX OR PHILLIPS HEAD SCREWS. GET A NEW ONE BEFORE YOU START FOR IDENTIFICATION & COMPARING. GOOD LUCK, DR VOLT.

Fan motor very loud at low speeds


sounds like something inside blower fan that should not be there , higher speed causes outward force inside so that whatever is in there is forced against the blades and therefore is not as loud
