Hello and thank you for your question. The smell you are having is a result of a dirty cabin air filter that needs to be replaced. The filter is under the dash behind the glove box. If you continue smelling anything afterwards, then look in the engine compartment for any issues with wiring or the fan motor wiring.

If you need assistance finding the smell, then seek out a professional, such as one from YourMechanic, to help you determine the source of the smell in the car.
