How can I repair vibrator in Pebble Time?

I'v turned on my Pebble Time for the first time and, as I remember, vibrator wasn't working from start. I tried turning quiet time settings on and off, changing vibration intensity, resetting, factory resetting, charging while resetting - nothing helps. Microphone still works - meaning, I suppose, problem is in vibrator itself or it's connection or motherboard problem. Are there any vibrators which will fit as a replacement in case I could not solve this problem another way?
