Here are some specific explanations for why the 4x4 light might be flashing on your Ford Explorer:
* Low fluid levels: The four-wheel drive system in your Ford Explorer relies on fluid to operate properly. If the fluid is low, the system will not be able to properly engage the four-wheel drive system and the light will flash.
* Damaged sensor: The 4x4 system also relies on a sensor to monitor the position of the transfer case. If the sensor is damaged, the system will not be able to determine if the four-wheel drive system is engaged and the light will flash.
* Problem with the transfer case: The transfer case is the component that transfers power from the engine to the front and rear wheels. If there is a problem with the transfer case, the four-wheel drive system will not be able to properly engage and the light will flash.
If you see the 4x4 light flashing on your Ford Explorer, you should stop driving and have the vehicle inspected by a certified mechanic.
