When I start to push on the gas peddle it makes a rattling noise. Why is it doing that? And my a/c works fine but it won't come out the middle vents in the front but comes out the defrost floor board and the back vents.

pull your hvac fuse for 60 seconds with key on sometimes this resets the actuator in the hvac unit which is why it comesout the defrost. or if this vacuum operated check for a vacuum leak.as far as the rattling noise, check belt nd tensioner by spraying water on it if it stops replace the belt and tensioner

need a bit more info on this rattle... if you press on the gas in park, does it do it? or more so while taking off from a light? (engine under load) also, do you hear/feel this rattle more to the front of car, or middle, or rear???
