My 2004 Impala Sedan bought new almost 2 years ago, 3.4 motor, 79,000Km, has
developed a water leak on the front passenger side when it rains or when I
use a generous quantity of windshield washer.
It looks like it may come from the air vent under the glove compartment.
But I'm not certain.
I'm concerned that the water might get into the electronics. If there's
someone in this knowledgeable group who has seen this problem before I'd
appreciate any input.
Has the cabin air filter been replaced recently? It's under the cowl
below the windshiled and has a piece of weatherstripping to prevent
water fron entering. It's a quick fix once you remove the cowl

Not all Impalas have the filter, it was optional on the base model so it
can't be what keeps water out otherwise all the base models would leak all
Try cleaning the leaves from the little grill by the right hood hinge that
you see on the plastic at the base of the window when you open the hood.
When ours gets too many leaves in it the water backs up and leaks in where
the filter would be installed.
The weatherstripping is seperate from the filter, should be there on
On a related note, the '06 GPs have a plastic deflector over the
filter, to help prevent water fron entering through that opening.
There's still openings for air to enter, just not through the
Ohh, your your not talking about the weatherstriping/seal on the filter
then. On ours the seal between the cowl and window was nasty with dirt and
crap in it and it looked like the glue has melted in some spots and let it
move around some when I last pulled it off (I had bought one of the filters
and put in but it cut the airflow down some so I pulled it back out). I
cleaned it all off and replaced it with some of the $.99 stuff from the
But ours would leak because the cowl drain/vent on the right would get
clogged up and the water would run across the cowl and down between the
joints where the right and left meet and once I clean the vent out it stops
I found the problem: the long black piece of plastic at the base of the
windshield holding down the weather stripping is warped, leaving a large gap
where the wiper sits. As a temporary solution I cleaned the area with
rubbing alcohol and put several long strips of black electrical tape to
close the gap. No more leak.
Next time I go to the dealership for an oil change I'll ask them to replace
Thanks for the responses.
(Just for fun, do a search for "Impala water leak" on Google. It's sort of
a common problem.)
Alright -- so I found that piece black piece of plastic at the base of
windshield as well -- and mine was slightly of so I glued it back on
again. Today we went for a spin for a few hours in nice hot sunny
weater and the buttom of the fan was all wet again. could it be that
there is a drain problem with condense water from the AC Grill in the
car? Does anyone have any experience with that?
Please let me know --
Thanks loads :)
Well wouldn't you know it -- I thought I would have another look to see
if I could find the AC / Drain -- and I found this little 90 degree
angled house 1 foot below the backside of the alternater -- I pulled it
of and got a quart of a gallon of water out on the ground -- the hose
was plugged with dried dirt / dust -- I cleaned it out. Hope I am all
good now -- if anyone else has any other thoughts please let me know :)
