Toyota Sequoia 4Lo light blinking, unable to shift into all wheel drive on Toyota Sequoia

Some Toyota Sequoia owners report experiencing issues with the 4Lo light blinking and an inability to shift into all-wheel drive, indicating a problem with the 4WD system. This issue can manifest suddenly while driving, at startup, or during maneuvers like switching between 2H and 4H, despite the vehicle being drivable. Some owners have found that restarting the vehicle may temporarily resolve the blinking light, while others have discovered a workaround involving turning off the car, switching to 4Lo, shifting to neutral, and then restarting to attempt shifting back into 2WD. Troubleshooting may require warming up and moving the actuator by following specific steps, such as pushing the 4Lo button and listening for the actuator attempting to shift. It is advisable to consult a professional for further assistance if these problems persist.
