Alla lainaus Matthesin Volvo sivulta korjaustopicista: Voisin olettaa, että puhutaan saman asian aiheuttamasta melusta uudessa motonetin puhaltimessa, mikäli se asennetaan uuden asennusmuovin kanssa.
There is a subtle fan motor noise that was not heard with the old unit, but the noise is so subtle that I don't notice it over any normal car noises (road, radio, etc.). I assume this is because the after-market device purchased did not have the rubberized mounts within the motor housing as seen in the earlier pictures (the old housing had the soft white cushioned material and the new motor housing was strictly ABS type plastic).
