In a Lexus GS300, if the AC is blowing cold air on the passenger side but not on the driver side, it may be due to a malfunctioning blend door actuator. This actuator controls the flow of air between the temperature zones, and if it fails or gets stuck, it can prevent cold air from reaching the driver's side. Additionally, issues with the climate control system or low refrigerant levels could also contribute to this uneven cooling. A thorough diagnostics check is recommended to pinpoint the exact cause.
