Aircon mouldy smell
I'm at a loss how to cure a mouldy smell from my aircon / ventilation system. I've used Forte treatment twice and the pollen filter was changed at the last service. I've also done the 10minutes full heat trick a few times.
There is evidence of dye on the outside of the compressor unit. Could a slight leak be the cause of the smell? The only other thing I can think of is that the dealer changed out a leaking windscreen washer bottle before I bought the car. Could residue from a leak still present in the engine bay be responsible?
Any suggestions gratefully received!
