We just started getting a cow manure smell when the heater or AC is on. Does this vehicle have a cabin filter?
What could this smell be caused by and what would be the least expensive step to try first, second and third.
Do you
have the same problem?
Yes
No

The smell from the heater may smell like mold or mildew, but the ac definitely smells like cow manure.

Check that the A/C drain tube is not blocked, you can get a vent system sanitizer that will kill any unpleasant smells, this is often a fungal growth in the vent system due to poor drainage. A dead rodent in the system is far more offensive.
