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.
