gear of the car is not changing to 4 wheel drive any one can please tell me what is causing this and how or what i can do to fix this?

before taking this anywhere go to Rashidya Opposite Festival City there are good garages in a line and will see the problem. dont delay and dont experiment.

running and 4x4 turned on disconnect the vacuum line at the hub and check the vacuum suction

If there is no suction then check the vacuum lines from front wheel hubs for damage

If you have a good vacuum it may be worn so take them off, clean, and degrease
