A harmonic balancer (as stated) would only get worse at higher rpms and cause vibrations, not noises. Have you had the hood opened and look/hear around for noises?
yes i have the noise sound like its coming from the belt area But it being cold outside i havent got into it more yet ( i dont have a garage) which sucks!!!
before you condemn the balancer inspect it for broken parts. usually the balancer would cause vibration not a rattle. you need to do a visual of
brackets,heat shields,exhaust.. you need to try and pin point the area of origin and when it happens. unless you are sure its the balancer.
good luck and keep us posted. C8-)I agree with college man, your first step should be to isolate/pinpoint the source of it. Good luck and keep us posted!
yes that is what iam going to do can i take that belt off and start the car and see if the noise is still there? by taking the belt off that would tell me right away if its that or something else?
It can be easier to inspect it with the belt tension off yes but if it’s obviously bad then you should be able to wobble it with your hand anyway. A good pulley will not wobble in any direction. Did they explain exactly what was wrong with it? $1000 to replace a crankshaft pulley seems a bit extreme. I can get my timing belt and drive belts replaced for less than that and they have to go past the balancer and about 10 other components. That’s my opinion.
Here are a few video’s by Eric that aid in your diagnosis.

I would definitely do a good solid visual inspection also.
yes iam not sure why the shops wants that much i bought the car cheap and this is what the owner told me
So can i run the car WITHOUT rthe belt on?? of course this would be for a short time to see if it makes the noise of course if it dont make the noise then i know its not the balancer will for the most part unless it needs to be unload to make the noise….lol
+1 all to college man, dreamer2355, and djdevon3!
To answer your latest question, you should be able to start your car without the drive belt (i.e. serpentine belt) on the vehicle.  
I feel ya on the no garage. I’m in the same situation. Between having free time, dodging the rain, and trying not to get sun burn it’s a real pain. Can only hope that someday you’ll be in a position to have a garage. Keep hope alive. 🙂
+1 Beefy. If there is a problem with the harmonic balancer then running the car will only make it more evident. Check all the pulleys. You can do this in 2 minutes even if it’s snowing and lightning outside. Pop the hood and use your hand to try and wobble each pulley. Check each pulley for wobble. The harmonic balancer is much bigger than the other pulleys though so you’ll need to put extra effort into trying to wobble that one. If the pulleys don’t wobble then your rattle is coming from elsewhere.
Maybe take some video so we can see and hear it too? If a picture is worth a thousand words then video is worth a million.
+1 on Dreamers post to help you find the source of the noise. You can run the engine without the belts attached just don’t do it for too long, I think that’s a good place to start looking since you feel the noise is coming from that area, in fact if
