vibration motor failure? - HTC Rezound

so I've unlocked my boot loader and am running the latest INFECTION rom by neo.
I've noticed, probably for the last couple months at least, that if my phone vibrates a lot (ex, in vibration mode, getting alerts a lot from instant message, or toggling vibration in status bar toggle back and forth), each time it gets weaker and weaker.
but after a while (possibly hours, could be less or more, Idk), it gets stronger. at least until it starts being used again, then it gets weaker as it is being used.
I've been running custom roms pretty much since I started using this phone, in November '12.
so the question, is this a hardware problem, or could it be fixed going back to stock?
if hardware, is replacing the motor a viable solution? is it soldered to the main board?
I appreciate any input on this matter, thanks!

it could be a couple of things...if this has been an ongoing thing since you started flashing last year...it may be roms as some have different haptic settings...but if its just very recent the hardware could be failing or it loosened itself outta the housing in the inside....i know a few people on here who have changed their motors and where they got it...its on either the rezound general, q&a, or accesorries thread

well I don't remember exactly when it started, but I remember realizing that the vibration would get weak if used too often. I suppose it happened all at once, but it might have been gradual, and I only just noticed it once it reached a certain threshold.
I'll see if I can find the threads you're talking about. but if you find them first, you could post them

Ya sounds like its hardware related...give me a little and I'll dig the links up for you...I'm in the process of packing as I'm moving over 3000 miles away from where I currently am on Saturday

thanks! looked on eBay and ordered one for less than $4, sounds like a straight forward install with only 6 screws.
it'll be nice to have reliable haptic feedback/silent notifications again.

I have experienced the same symptoms, and I'm running the stock Sense 3.6 ROM (rooted). But for me, it's on and off: it'll do this for a couple of days and then be fine for several weeks. I'm not worried about it anymore. At this point it's been going on for almost a year, I'd say, and vibration hasn't ever fully stopped working in all that time.
So that at least confirms that it's not ROM specific.

It's never come to a dead stop, it's just been extremely week at times.
I'm really hoping it's not the main board failing to supply the right power to the motor.
So what happened, the motor I got on eBay was DOA (tested it with strands of wire as probes). My old motor turned on at a couple volts, but the other one was completely dead. (Unfortunately I took my rez apart twice cause I expected it to work, lol).
I did a stupid thing I suppose, I tried to use my old motor's brushes on the new motor (after accidentally opening the broken one up and seeing it spun with my test leads). Long story short I ruined my original motor, so I have absolutely 0 haptic/vibration on my phone right now. Let me tell you, it's really annoying! (Especially pressing back )
Well I got a refund from the seller and bought a new one yesterday but it won't be shipped till Monday.

Thanks again! Just got a new motor installed and it works great! (It's crazy awesome to have haptic feedback again)
I bought one for the HTC amaze 4g, and cut off the connector and soldered my old one on. Put some heat shrink on it and installed it, and that did the trick. Good thing there's a little bit of extra room under the back cover!
