Horrible damp type smell when turn off cabin re-circ

[gbrall]

Recent hot weather have had the AC on and cabin re-circ. Now back to the normal scottish crap weather just put the demister on with external intake and there is a horrible dampy stale smell coming into the cabin, any advice how to sort, new cabin filter fitted and no change. Thanks.

You can buy aircon cleaner, I think Wurth make it, it has a very long plastic tube that sprays disinfectant into the evap. unit and cleans it as it drips out the condensate tube.
I would start there.

I would turn it off and leave the car outside in hot weather with all orifices open (boot/bonnet/doors) to let the moisture evaporate as much as possible

There was a claim of old still water stored in cars (often the container for windcreen washer fluid, a plastic pouch like a hospital drip) that bred either Legionnaires or psittacosis.
