Phone not vibrating

[mommasboy]

Hello all,
I dropped my phone yesterday and the battery came out, but to my surprise everything looked good. No scratches dings or anything, so I picked it up and put the battery back in and noticed that it didn't vibrate when it booted up. Once the phone came on I soft reset to see if that would fix the issue, It didn't. Next I hard reset, and it still didn't fix. I was running a custom rom so I flashed back to a sprint rom and still nothing. I tried putting the phone on vibrate and calling myself and nothing. Everything else on the phone works. Is this enough of a reason for sprint to give me a replacement, free of charge or will I be required to pay my deductible. Any help is appreciated.
