Vibration Fustration

My wireless control stopped working!  I mean, it works, just that the vibration feature seems not to be working.  I've had the controller for atleast 3 months, and it worked fine.  I was playing baseball the other night, and I saw the x-guide button thing flashin.  So I went to check it's battery life, it was fine.  Then it does it again, so I pushed the button on top of the controller to make it stop.  Its the button where you try to find a connection with the xbox.  Then I went to make the pitch, and normally it vibrates to let you know the release point, nothing happened.  So I plugged in my wired controller, and it worked fine.  I used my other wireless, worked fine.  But I want to know, is there any way to turn of the vibration in the controller with out going through the game and turning it off?  Or is my controller, messed up now?
