Question: Musty smell when turning on the fan and/or a/c.


For a couple of months now, I am getting a musty smell when I turn on the fan and a/c. If the AC is turned on, then the musty smell goes away after a few seconds. If it is only the fan, the smell remains but gradually goes away. I had a local mechanic attach some type of flushing system to the evaporator and treat it. The mechanic said he did it twice. It helped kind of for a while and now the smell is back. I have been trying to use Lysol and that helps but for a short duration only.

I did confirm that the drain plug is not blocked. I am able to see water dripping out after using the a/c and the car is brought to a stop.

I was wondering what is the next thing to do and how much that would cost.

Any help and advice is appreciated
