If your car smells like gas when you turn on the AC, it could indicate a fuel leak or an issue with the fuel system. The air conditioning system may be drawing in air from outside the vehicle, bringing in fumes from a leak in the engine compartment or fuel lines. Additionally, a malfunctioning evaporative emissions system could also contribute to the smell. It's important to address this issue promptly, as it may pose safety risks.
