Volvo V70 - Volvo bad smell from vents - Gregory II

A friend of mine owns a Volvo V70. There is a bad smell coming from the vent. The cabin filter was changed. What else might be making the interior smelling, and can the air conditioning be to blame for this at all?

Thanks

Greg

Most probably a block drain in the condensor AC or just mouldy. There are treatments available. Post on www.Volvoclub.org.uk in the appropriate section. Regards Peter
