Nasty sweat like odor from HVAC system when engine is off?
Need some help here. I've had this issue for a while now but kinda put it off since it only occurs when I have the fans running with the engine off.
Basically whenever the air is actually being heated and/or cooled, the air from the vents smells fine. No odor at all.
But once the engine is off (or I turn off the AC) and I have just air blowing, it smells like sweat or some kinda body odor. Like a moldy smell maybe. Doesnt matter if I have recirculate on or off.
I just replaced the air filter this month and I still get the smell. New air filter does have carbon.
Any ideas? Wheres the air intake for the ventilation located? I should probably check that. I'm close to just running the vent on full blast, taking out the air filter, and spraying febreeze into that gap, hoping it circulates and kills whatever is causing the odor.
