Whenever I turn on my a/c there is this vibration kinda sound. Actually its kinda like if you turned on a fan and touched the blades. It sounds like the blower motor and it gets louder when the fan speed is higher and it goes away when the fan is turned off.

I guess my real question is could this be attributed to the infamous leaking water in the a/c drain? Or is there some way something could have gotten into the blower motor? I haven't noticed any water leaking and the a/c cools fine, its just the noise that worries me. It isn't really loud, but it is kinda annoying...

 

It's the infamous A/C drainage backed up. Since it's clogged it tends to get backed up into the fan causing friction w/ debris. Have it cleaned out at the dealer and it should take care of it!
