Electric whirring noise when starting up car?
zpyder:
Im a total noob when it comes to cars and the likes. I drive a micra, enough said.
Anyway, for the last month or so, my car has started to make a strange whirring noise sometimes when starting it. Typically its when it hasnt been driven for a few days, or like today, when it was really cold.
The noise is very similar to the whirring noise you get when using the windscreen washer jets.
What happens is, I turn the key, car starts, and then a split second later I get the whir noise for maybe half a second or so? If it were the starter motor or something surely itd whir before the engine kicks in, and not a split second after?
Any suggestions appreciated, as its not done it before (5.5 year old car) so Im presuming something is going wrong rather than it just aging...
knighty:
have you changed the battery since you got it ?
(iirc you got it new yeah?)
its probably just the battery getting a bit old... the cold weather doesent help so theres a bit more load on the alternator to charge up the battery again just after youve started it
nothing to worry about... its probably a pretty small battery on yours so you might as well change it sometime, but theres no hurry.... if youre not going to do it yourself then just wait till the next service etc.. :-)
zpyder:
I think its had new batteries at various services over the years, I dont think the battery can be any more than 2 years old (CBA to look in the service book as that means going outside)
mr_roll:
Is the noise when you turn the steering wheel?
Is it just when its idling?
Where is the noise comming from?
Oh, and whats on at the time of starting up? Demister? fans? heater?
zpyder:
Nothing on, nothing being turned (wheel)
Literally I get in car, put key in ingnition, turn the key, car starts and ~0.5 secs after ignition I get about a second of this electric whirring.
no headlights on, no wipers etc, just standard "on"-ness
