Bacteria in the AC matrix, an aircon sanitiser bomb would fix that easily in 10-15minutes and available from all good motor stores.

My guess is that you have mold growing in the vents / ducts. If you leave the AC blasting on cold until the moment you turn the car off, the condensation stays in the vents and can allow mold to grow.

Ignore the long-winded, nonsense "answers". When was the last time you changed the cabin filter? Most people don't know it's there, or don't change it hecause of the expense. But I guarantee that if you replace the filter and have the evaporator cleaned, it will be good as new.
