Can you explain a little more about the problem. Does it not vibrate or does it not go into vibration setting?

If it does not vibrate and you have excluded the vibrator itself as cause of the problem you can check the following
- Make sur the vibrator pads on logic board are clean and can make good contact with vibrator springs.
- Continuity between vibrator pads and the 2 small capacitors next to the vibrator pads.

If that is OK then the problem lies most likely in audio chip U60 which is responsible for driving the vibrator. There are no fuses on the logic board. Vibrator is directly tied to chip U60: replace U60.
