The vibrate motor is at the top right-hand corner of the iPhone frame (when looking at the back of the iPhone). It is secured by 2 screws which hold the two springy connectors down on the pads of the volume button/headphone jack flex assembly. This has NO impact on your home button under any circumstance. The home button connects to the charging dock connector, which connects directly to the motherboard. Your issue does not make sense. Is there any other information you can provide to help us answer your question?
