Try engaging the 4wd H when the vehicle is rolling slowly and in gear . Sometimes if the unit is actuated the gears will not line up an get stuck on the end of each other and will not mesh. If the gears are turning this is unlikely to occur and meshing is easier.. have the actuator checked (part that actually does the changing) and check the wiring or vacuum hoses if any used as there may be a leak or wiring /connector problem ( water /moisture/ dirty pins etc)
