Default noise when turning key to put electric on before starting engine

Got an '02 here. This noise started to appear recently.

When I turn the key to put electricity on (without starting the car), I hear this electric motor-like sound, similar to power window sound, coming thru the dash area, and it can also be heard outside the car coming from somewhere in or near the engine compartment or in front of the dash/windshield area.

Could this be one of the servo that operates the AC vents? or its something else?

any clues?


thanks

There are a few items that it could be. When the key turns to on, the fuel pump is activated, the headlight levelers could be activated and it is possible that something in the a/c is activated.

My '02 makes those noises also.

Welcome to the forum, BTW.
