Answer
hello, the 4 wheel drive actuator in the transfer case may be stuck, or the front differential actuator. locate the transfer case actuator, it's actually inside but you can try using a rubber hammer or a metal hammer and tap on the case where the actuator is located while someone inside engages the 4 wheel drive, this may loosen it and let it move to engage the transfer case.
