Our 2001 Volvo V70 has just started making a whining/clattering sort of
noise with the ignition on but not with the engine on. it seems to be
coming from the front nearside area of the engine compartment, in front
of the fuse box area by an air assembly of some sort. It is some sort of

motor I guess.

All the things are off inside - eg aircon, which i thought it might be
something to do with.

Any ideas?

Thx

E.

Does this happen when you first turn the ignition on, when the engine is
cold - or only when you turn the engine off after a run? If the latter,
might it be the electric fan on the radiator, which sometimes keeps going
for a while after the engine has stopped?

Your term "nearside" is dependent on whether it's a RHD or LHD car! Please
define which side you mean in terms of right or left when facing in the
direction of forward travel, or somesuch.

It happened this morning for the first time from cold on the way to work. I
haven't started it again yet but it's loud enough to hear in the car and
alarmed me enough to open the bonnet (hood). It was OK yesterday. It's a RHD
car in the UK, and it's a 2.4 petrol engine.

I get the same noise, but only after washing the windscreen on the previous
usage.
In my case, it's the headlamp wiper parking itself correctly. When I wash
the windscreen the N/S (UK car) headlamp wiper parks in any old position
and corrects itself when the ignition is turned on before I start the
engine. Must fix it some day as that's the one that's easy to get at.

Take a look at the front of the car before you next start it.

Having slept on it, i thought you should check the headlamp leveling motor
on that side also. With ignition on both headlights check their positions
relative to what the levelling switch is telling them.

Ah, yes it does appear to be the wipers, on both sides now. but the
motors stay on and the wipers don't move i think. They are facing
outward - is the park position inwards?

<short delay while I go and look/>
Not on mine, they park against the stops on the outwards side of the
headlamps, at the base of the light.

If the motors are on and the blades aren't moving, is the nut done up
tight? (Oh, Ah Matron :->)

Hmm, so they are parked as yours are. Why on Earth would the motors turn on when
the ignition key is turned to the first stop?

I expect that when power is enabled to a motor and the motor isn't at its
home position (in the 'park' segment of the rotor) then it will try and
move to that position.

If this happens every time the ignition is moved to 'accessories', have you
tried getting someone else to turn the key while you have a look under the
bonnet / front bumper until you isolate where the sound is coming from? It
might be, as Tim suggested, that it's the headlamp leveler.

The only way to be sure is to keep listening until you've identified the
source.

Well, it is the wiper motors - garage says they were knocked back by an
impact. This is correct - a bread van shunted our parked car a month ago -
so this must be a delayed reaction. I should be able to extend the
insurance claim (garage wants £98 + £60.50 labour for each motor and says
there is no repairing them).
