Hello,

I have a 1994 Grand Am GT, have owned it for 3 years now, and bought it from
my cousin who was the original owner. Since I have owned it I have noticed
every time it rains, the belt seems to squeal fairly often. I figured the
water was splashing up on the belt from the wheel.  When it squeals, the volt
meter jumps down, and the headlights dim.

Over the past year, this has gotten worse. Now the belt squeals even when
it's dry outside (but not as often). And the volt meter will jump down
(slightly above the red mark) and up, even while travelleing at constant
speed on the interstate.  I replaced the fan belt about 8 months ago, and
that seemed to help for a short while, but it is not back to the same way.

What is the most likely cause of this? Also, is there supposed to be a guard
or something that keeps water from flinging up onto the fan belt?

Thanks!
Donnie
