Problem overview

Some Mitsubishi Mirage G4 owners report experiencing issues with fogged-up windows during damp conditions, finding it challenging to maintain clear visibility. Many have discovered that rolling down the windows slightly can help align the interior air with the outside air, thereby reducing fogging. Additionally, some owners recommend using the defroster at a lower setting to assist in preventing fog on the windows. Keeping the windows clean from oil and dirt is also noted as a critical factor in minimizing fogging. Furthermore, some owners emphasize the importance of checking for leaks that could contribute to excess moisture inside the vehicle, as well as regularly airing out the car to maintain balanced humidity levels. By implementing these strategies, owners can effectively manage foggy windows without solely relying on the air conditioning system.
