If the vent selector in your Toyota 4Runner isn't working, it typically means there's an issue with the blend door. This door is responsible for directing air within your vehicle's HVAC system. When the blend door malfunctions, you lose control over where the air flows. It operates by opening and closing to direct air to different parts of the system with the help of an actuator. When the actuator malfunctions, it can cause the system to be stuck in either an open or closed position, preventing air from flowing where you want it to.
