Looking for help from the car guys here. My vents in my 2012 Mazda 3 are blowing something out of them that kind of looks like smoke but doesn’t smell and sinks instead of rises.
This happened before and I replaced the cabin air filter which seemed to have helped for a while. See video
We have had a ton of pollen in the air here that may be getting in. The “smoke” doesn’t smell or feel hot. No hot temp warnings from the engine compartment. No smoke under hood. Case has oil…
I am at a loss. Anyone have any ideas?
Let us know if that resolves. I’ve put in a few vintage ac systems and they are really not that complicated. I can’t see it being smoke unless your blower motor is the problem. It’s likely vapor from pooled water.
Follow up - cleaned out that drain line about 1.5 weeks ago (there was some crud in there). Have not had the issue since, but it’s also been a bit cooler here so I don’t know if I have been running the a/c as hard.
