What cause the all wheel drive not to work?

Several factors can cause all-wheel drive (AWD) to malfunction, including a faulty transfer case, damaged driveshaft, or worn-out differentials. Issues with sensors that monitor wheel speed or traction can also disrupt AWD functionality. Additionally, low fluid levels in the transfer case or transmission can lead to inadequate power distribution to the wheels. Regular maintenance and timely repairs are essential to keep the AWD system functioning properly.
