Nasty vent smell in 2018 Chevrolet Equinox



I have a 2018 Equinox.
I am getting a nasty smell from my vents when I turn on my air. This has been happening since our weather changed and the temperatures started going up. These last couple of hot days, I have run the air more than I usually do. Today, I’m smelling that same odor on my cloths. This is not good!


You may have rotting leaves or a dead mouse in the vent system of the car. You may also have a plugged drain in the AC system allowing buildup. I’d suggest filling up a gallon bucket with warm water and cleaning solution (not bleach - I like Odo-Ban) and pouring it onto the base of the windshield. That’s where the air intake is. Rinse off the painted areas it touched but don’t hose down the vent area. Let it sit overnight and rinse it off in the morning. If that helps but doesn’t remove all the smell, you can treat it again.

If that doesn’t help, take it to the dealer to have the drain un-plugged and the cabin filter, if it has one, replaced. This isn’t warranty, you will have to pay for this.
