I absolutely love my 2008 Impala LS. The car has been without a doubt, flawless. I've maintained it, changed the oil, etc. A few bulbs replaced, wipers....etc. Easy
This Impala, and I have discovered, other Impalas as well, have an apparent inherent problem: When it rains, the front, in-the-door speakers die. Once they dry out, several days later, they begin to work again, at least one of them works again. The passenger side is pretty much dead. I have read on Impala forums this is a common problem, apparently some believe that rain enters the door through the mirror mount??? Others have no idea where the water is getting in. No one seems to know the solution. Hence, I am here a midst the genius group.
Since OnStar relies upon the front speakers to work, rain basically renders OnStar pretty much useless. This includes the built-in telephone, if you use it. These two functions are routed through the car's front speakers and when they go out, OnStar become useless. You can still hear very slightly, OnStar, but it's coming through a very tiny speaker, but I have no idea where. Even the turn signal "click" ends up sounding lighter and smaller, if that makes sense. You can barely hear it.
Does anyone know if there's a way to re-route OnStar and the telephone system through the rear speakers? Or better yet, does anyone have an idea as to how to fix the leak before it rots my doors?
