Why Does My Car AC Smell Like Fart?

There are multiple factors that can cause a car to emit a smell similar to flatulence. Some possible reasons include an animal being trapped in the engine bay, the presence of molds and mildews in the AC vents, a clogged catalytic converter, a dirty EGR valve, or a coolant leak.

If you notice the smell of gas in your car, it is important to promptly turn off the engine and exit the vehicle as quickly as possible.

Is there a possibility of a gas leak in my car's AC system?

There are several reasons for car AC gas leaks:

One reason is corrosion of the refrigerant lines due to exposure to fluorides and chlorides. Another reason is mechanical damage caused by impact or wear and tear on the refrigerant lines. Additionally, a malfunctioning or leaky Schrader valve, used for adding or removing refrigerant, can also cause leaks. Leaky connections or poorly soldered fittings on the control valve, which regulates refrigerant flow, can also be a contributing factor. Finally, a damaged fuel tank can cause gasoline to leak and enter the cabin through the AC vents.
