Bad Smell Coming from Air Vents

What kind of smell? Is it sweet? With AC or Hear or Just vent on? If it's sweet with the heater on, it's the heater core. Is your anti-freeze low?

The smell is not sweet. I have the climate control set on automatic with the temperature set for 72. My wife says the smell is something like horse manure. It seems to be coming out of the air vents on and under the dash. Al

And if it smells like BO in all modes it could be blocked condensate drains and mold/mildew has begun to grow in the moisture.

Check your muffler. I once somehow had a plastic bag get stuck to my muffler and the heat melted the bag and what ever was in it.

Smelled awful, just as you described. Had to get under and scrape off the stuff. Took a long time for smell to disappear.

I get the BO smell after using the AC for short trips. Then the smell will be in all modes for a short time. How can I check/flush the condensate drains?

Don't use your A/C on recirculate except for short cool-down periods. That encourages mold growing there in the moissture that accumulates.
