I also have a problem with the blower of my aircon, everytime that i start my AC the air that comes out from it smells bad. Amoy basang basahan na naiwan ng ilang araw, then after a minute the foul odor is gone.
Whattya think guys is the problem???
Molds.
Temp fix would be as simple as a can of Lysol and about 15 minutes.
