Noise Suppressor from blower unit fan, through the radio?

[Aurion ZR6]

It has only just start a few weeks ago, I've the Navigation unit/ Radio, and I'm get the blower unit fan noise through the radio?

If I turn of the blower the noise stop.

I'm looking under the electrical drawing and cannot see any noise suppressor?

Also I cannot find the blower unit fan circuit is this under Air Conditioning in the Electrical?

Can anyone tell me is there one in the radio circuit, as I cannot find it, or I need to put a noise suppressor on the blower unit fan.

Cheers Drew

Right I found the Blower unit fan wiring diagram under A/C pdf page 386 there appears to be no noise suppression on this circuit.

Look like I've answered my own question, I will now add a noise suppressor to the nav unit circuit.

Still not done, and 9 years have passed, I'm so lazy, might get around to this very soon, its driving me mad listerning to the sound of the fan through the radio.
