s60: blower knocks
I've got an '01 s60, and in colder weather only, the fan blower
knocks. I've had this in other cars, and I remember having to
take out the blower and clean the cage.
Would that be the problem here? The Volvo, unlike my other car,
seems to be "mouse proof", so I don't see why the cage would have
debris in it.
If this is the solution, how hard is it to do the job (and where
is the blower, for that matter)?
