Perhaps this is another stupid question from me .

Whenever my ignition is turned on I can hear what sounds like a small fan running, even if the engine is not running.

It comes on before the engine starts and turns itself off about 5 seconds after the key is removed from the ignition

It is not as loud as the fan that I hear when operating the heater of cold air blower .

I don't know what it is or how to turn it off.

Any ideas ?

thanks

Today somebody told me that the cd/radio has a small fan.

Perhaps this is what I am hearing ?

Very odd

I. Am looking at the back of a recently removed NH3T-W55 stereo unit there are 2 fans fitted chances are this is the noise.

Thanks for that, it probably is them.

Seems strange it cant be turned off when not in use.

I've been hearing something similar recently. It comes on when I start the engine and stops once I start driving at speed. Comes on again when I'm slowing down. No idea what it is.

Same on mine, like a fan stuck in same position but trying to move 

Just checked mine it starts when the air con is on... And goes off when i turn it off
