power steering pump got 'whirr' sound

[kippo]

hi,
i have been wondering where is this motor whirring noise comes from. I thought initially it is from my driver side mirror flip motor.
recently i winded down my window when parking d car, then i hear the power steering pump whirring sound. The fluid level is at maximum.

do your MPS power steering makes that whirring noise? or is it very quiet?

It because they are electric pumps

'Leco pumps is the reason behind the noise.

Mine is most audible when I park it in the garage after the drive home.
